[Q] Problems installing / removing and updating apps - Ubuntu Touch Q&A, Help & Troubleshooting

Hi! I have been using touch for some weeks on my nexus 4 now and it is working all-right for me. Unfortunately i cannot update install / remove apps any more. When i try to update the apps via the system settings nothing happens. When i try to download an apps via app store it says cannot download. Removing "seems" to work but when done - the app is still there - even after reboot. Can anyone help me? Would be great!
Ah another thing - adb shell was working fine but stopped working as well - i get "device not found" now...
I think the File-System might be read only?

You need to re-add your Ubuntu One account and installing apps will work again.
To use adb you need to enable the developer mode in System Settings > About phone > Developer Mode.

I too am having problems updating my apps. From system settings, I have 18 updates that will not work when I tell it to. I have them on auto-update as well.
sudo apt-get update
does not work either

@Xinthose Have you tried readding your Ubuntu One account as well? That was needed due to some code changes introduced a while ago.

That worked, thank you. Why doesn't sudo apt-get update work?

@Xinthose Due to the way system updates are done, "apt-get" doesn't work for now. Since they, however, plan to use the same update method for the desktop in the future, they will at some point have to add apt-get support. They already talked about how that would be done on the ubuntu-phone mailing list some time ago.

Just forgot something: You can actually make apt-get work (and everyone working on the core system components actually has to do that to test their changes) but that breaks system updates.
To do so you need to make the image writable (look for the how-to on the Ubuntu for phones installation page). You can flash back to a non-writable image later but that always comes with the risk of data loss. So it's definitely not recommended for anyone who is not a developer!

OK, thank you. To make the phone work exactly like Ubuntu would be nice. What is the password for sudo / su ?

@Xinthose Just enter your device passcode/passwort.

[Q] Anyone get Ubuntu working...?

hi guys, i have an optimus v just lying around, and today i decided to try and get ubuntu on it through chroot.
using this guide, i was able to get to the point where it would boot on the command line,
Code:
[email protected]:/#
instead of the normal "#"
but after that, i tried to get it to work in a GUI, but it doesn't work?
i tried
Code:
apt-get update
and it runs, but gives me a bunch of fails and errors...
so of course, without that installed, i can't get any of the servers or other stuff installed, meaning that i can't get the GUI working...
so did anyone get this to work?
(i'm starting to think that it's their problem...)
thanks guys
i'll try to get a photo to show...
OK... First picture shows it booting into Ubuntu
Second picture shows the fail when I try the apt-get update command

hm that's weird... i have a wifi connection... i tried it on two devices and both could boot up linux, just not get the downloads?
hmmmmm...
what version of ubuntu? nvm, I see your screenshot says karmic, which should work.
more recent versions don't support armv6, so apt-get fails to download any unsupported package.
there's a thread in the optimus v dev section on installing debian.
squeeze and even sid run great on the OV for a 600MHz device with a tiny screen and no keyboard
try checking your /etc/apt/sources.list and make sure it's correct. It looks wrong to me, but I only use ubuntu for my DTV usb stick on my pc. I'm more a debian user myself.
edit again:
you can manually download .deb files and install them from the chroot command line with
dpkg -i filename.deb
just make sure they're for armel architecture; however, with ubuntu being too picky about the processor type, not all armel ubuntu packages will work. If you search google for ubuntu karmic armel whateverthehey.deb you should get stuff that will work. The main problem with manual installs is getting all the dependency .deb's, apt-get is really handy for that step.

ok, that sources.list entry in the screenshot looks REALLY wrong.
there is a stock version of the sources.list contents posted here
try putting that in there and maybe apt-get will work.

alright thanks... not sure if i get you completely...
i tried it on my actual phone (Mytouch 4G) and on a dell streak 7, both ARM7 CPUs and no luck on neither. i even turned off wifi on my MT4G and tried to download the packages through my mobile data, still no work...
so how would i go about getting the sources list on there..?
and where can i find the .deb files to install then manually?
thankss
go to the link I posted that says "here" and copy/paste the contents of that post into a plain text file named "sources.list"
put it in your ubuntu image (or partition, whatever it is) in /etc/apt/
as far as where to get .debs, google for what program you want to install, make sure to include "ubuntu karmic armel" in the search.
since you're using armv7, you can upgrade the ubuntu release without problems for those devices, the OV will have to stay with karmic I think.
your issue right now is that apt is trying to download from somewhere other than the default repositories, and it can't find where it's looking for.

you'll have to mount ubuntu.img as a loop device and put it in that directory's etc/apt/ folder.
probably can copy it in once running on-device, you'll have to figure out where in your filesysyem the img is mounted.
i'm not familiar with the method you're using so I can't be more specific, sorry.
alright guys FINALLY GOT IT!!
you have to replace the original server in

with this:

[Q] How to install an app on ubuntu touch

Hi,
I have just installed ubuntu touch on my Samsung galaxy s3 using the help of this link :
http://forum.xda-developers.com/showthread.php?t=2315397
Now, I have developed a small app using qt and ubuntu SDK on my system and I want to install (deploy) it on the phone.
I tried the instructions on the following links :
https://wiki.ubuntu.com/Touch/ReleaseNotes
http://askubuntu.com/questions/270832/how-do-i-install-an-app-on-a-device-running-ubuntu-touch
But the app did not run on the phone...
Is there any other way of doing it, since samsung s3 is not yet officially supported by ubuntu touch.

Does your SGS3 get detected under the Devices menu in UbuntuSDK? if so, go to build >> Ubuntu Touch >> Run Application on Device or just hit Ctrl+F12. if it isnt detected, i guess only the officially supported devices can run the apps.. contact me if u want to have a trial run of your app! il be happy to help! :laugh:

Well, there are bugs with the "Run Application on Device" feature. For example, it does not work with apps which have a C++ backend.
Workaround: Create a click package, adb push it to the device and pkcon install-local <mypackage>.click

At least it's the only workaround I know.
I don't understand it either. There are a lot of bug reports regarding the building process. Short selection of those which I found annoying:
https://bugs.launchpad.net/ubuntu/+source/qtcreator/+bug/1215937
https://bugs.launchpad.net/qtcreator-plugin-ubuntu/+bug/1299817
https://bugs.launchpad.net/qtcreator-plugin-ubuntu/+bug/1299797
Note that you won't have these problems if you build the package from the command line.
Just build in chroot from Qt Creator. Use the terminal to navigate into the build directory of the chroot (usually in <build directory>/ubuntu-sdk-14.04-armhf) and run
Code:
click build .
Then you can install it as described above.
EDIT: Note that you won't have these problems if you stick to QML without C++. Then everything should work fine.

apps and scopes available

hi im looking at maybe buying a ubuntu phone on the next flash sale or intsalling it on my nexus 5 and 7

so if i did RW and then update

Did you upgrade using the system settings update mechanism? That won't be blocked and the update will seem to work, but things will break after some time, just like your dual boot, especially when you start installing custom packages.
Theoretically, the application should work, but you're going to have to set up XMir properly to run X applications. If you are interested in doing that, the guy who made this video is the one who can tell you: https://www.youtube.com/watch?v=c3PUYoa1c9M
This video may be helpful, too: https://www.youtube.com/watch?v=XfMLzlki9XE
AND you'll have to install the devel-proposed channel as stable/rtm doesn't contain the necessary software yet.
I got root write - updated and upgraded and it killed my nexus 5 install basicaly wrote over the boot sector I think !
Can I not get a chroot for ubuntu apps I have on ubuntu and would they run? For example lithograph?
Ill take a look I've installed the sdk to test as well I'm certain these apps will get added soon scopes are great but being able to install ubuntu apps like lifeograph and other apps would be amazing.. Is this on the cards or do the developers have to release the touch apps version ?

I'm sorry for you killing your boot sector. Were you able to set up everything again?
I tried the chroot method some time ago but you still need to install the necessary packages for that using apt-get. So you need a writable system again...
You could, however, try to package the apps as a click package yourself. I've never tried that and I don't know of anyone who did, but if you ship xmir and the application in a click package, it should work.
I just had to reinstall and re-root was good really because got it set up right now.
I'm did a emulated rw and compiled lifeograph from source that it might work but it wont connect to mir using cmake there must be a use flag or ill look are cross compiling maybe.. Does it create a click package or a deb ? Ill take a poke around in apt cache to look at packages already cached from install

Great that you got it sorted out.
There's a trick to get the app working on Mir: Lifeograph is an app for the X window system. To make it run with Mir, there's a software called Xmir. Check out whether it's in the repos. If not, the source code should be online somewhere.
The app is probably going to compile as a debian package though. Either you stay with your phone in rw mode or you look into packaging it as a click package. The latter might be a little bit more difficult.

[Q][RESOLVED] Browser app settings and sync contacts

Hi ,
Yesterday, I installed ubuntu touch in my nexus 4 and decided to use it as my daily rom.
So, i tried to modify some settings. Everything is working well, however i have two problems.
The first one : I failed to synchronized contacts with syncevolutions. It's working but it synchronise only one or few contacs in my .csv file. As a solution i used google contacts sync. But if somebody have (or had) the same problem it can be interesting to share the solution with evryvody.
The second one : I tried to change the browser app settings, but it didn't work. I used these two websites to help me :
"bazaar.launchpad.net/~phablet-team/webbrowser-app/trunk/view/head:/README#L71" and
"lists.launchpad.net/ubuntu-phone/msg10301.html" I removed the first part, because i'm not able to post outside links.
According to the first website, we can change the homepage and the searche engine, you can use the second website to understand how to do it, i followed the instructions, but it didn't work for me. So, if somebody want to try or already have the solution, it would be amazing.
Thanks.
Edit : Apparently It is now possible to change the search engine directly in the browser (18 June update)
Although it's about calendar sync, this might be helpful: http://forum.xda-developers.com/ubuntu-touch/help/calendar-app-doesnt-sync-t3054933
What's the content of your browser settings files? I have that working fine for me here.
Code:

The file is automatically generated on devel-proposed build 166 now. However, it's called webbrowser-app.conf there.
If you're on the stable channel, expect that your browser settings will break in the future. However, you'll simply have to apply your changes to the new file then.
Hello,
I decided to install ubuntu touch again after all the new things they made.
However, changing the browser is no more working for.
I just wanted to know if there was another way to do it or if it was only my fault ?
Moreover, is that possible to uninstall preinstalled scopes like 7digital, amazon, ebay ... ?
@Remy.L There is just one browser for Ubuntu (except one third party browser). You can switch tabs by swiping up from the bottom edge though.
No, uninstalling preinstalled scopes isn't possible using the GUI as long as they aren't in the store.

Now I get what you mean with "changing the browser". There should be a settings option in the browser itself now (install the update from this week if you haven't already). Give it a try.
If there is still something you want to change manually, check out the contents of the browser's data directory. I think they renamed the settings file.

Sorry, i did not mean browser but search engine (replace google by duckduckgo).
I did not managed to have it working in the new version.
Anyway, do not bother you, i'm not using ubuntu touch anymore because i'm do not like that path they are taking with this OS (you can not uninstall what you do not want).
As i prefer to use open source software, the best thing to do now is to use an AOSP rom (or maybe firefox OS)
Thanks a lot for all your answers and have a nice day
PS: Sorry for my English, i'm not totally fluent

However, I guess that it is still impossible to remove unwanted stock scopes (however, as it is possible to remove unwanted stock apps, it may be possible to do it soon)

You could try removing them with the terminal-app like this:
Code:
sudo click unregister --user=phablet com.ubuntu.badscope
That should actually work. Pretty much everything can be uninstalled, even though not easily.

You need to find out the right package name of the amazon scope (given that it is installed as a click package, of course; I was unable to find it using "click list").
The reason why you don't see the option to change the search engine is that the devel builds are really, really outdated. I think they are half a year old or something like that. Either install the stable channel or devel-proposed.
Ok, thank you for all your answers, it may help a lot of people
Unfortunatly I broker my Nexus 4 screen last week (I'm planning to repair it but not yet [in few month]) so i can not try this rom right now.

Hi,
Yes, there's been a discussion about this on the ubuntu-phone mailing list recently. The reason why they can indeed not be uninstalled is that they are remote scopes with the code lying on a Canonical server and not on the device itself. I didn't follow the whole discussion, so if you are interested, check out the mailing list archive and you should be able to find the conversation within the first 5 pages.
Hi Nikwen,
So i checked your link and found what i needed
So yes, it is impossible to uninstall these scopes like you said, the only way is to keep it without using it.
But the thing i was thinking about is : If you do not use these scopes does it still get informations from you (in background) ? (because and do not want it to use my data continuously)
Sorry for all these questions
Have a nice day,
Remy
@Remy.L No, they won't be giving any information away. Scopes only run when they are in the foreground and even if they are, they are confined by a software called "apparmor", which means that they cannot access any data besides that which you enter into the search box. They don't have access to any of your private stuff.

[Q] ubuntu touch and apt-get

hi folks,
i am waiting for my mx4 and i have some questions
from what i ve read, as long as fs is rw we can apt-get install
but something puzzle me, can t find any example of ppl using aircrack or similar on ubuntu touch, isn t it possible?
thx for your time
Yes, you can install packages using apt-get when your system image is in writable mode. However, being in rw mode also means that you shouldn't install any system updates as they might break your installation. Therefore, you always have to roll back to read-only mode when a new image is available and reinstall all debian packages. You might understand that this can get quite annoying after some time.

thx @nikwen wonder in how long we ll have distro like kali getting ported to ubuntu touch, would be great!
so if i have understoud, what ever i install in rw, once i roll back to r only and update i loose it all correct? but on other hand if i am happy with my phone why upgrade
@nocomp Yes, you'll loose everything you have installed. However, since updates are comming only once per months, you could try writing a simple script which backs up your application data and another one which installs all software again and restores your data. That way it would be easy to upgrade your phone.
