[LINUX] Linux-on-Android project (incorporating Ubuntu installer) - Galaxy Note GT-N7000 Original Android Development

Please Note this thread is just for support to Galaxy Note owners, as this is the device I own and thus can give you much better support, for all other devices please uses the main thread HERE
The TEAM!
While for the past 5 months it has just been me its time to bring the project to a level I can't maintain by myself, cue the birth of the Linux on Android TEAM
The team consist of:
Myself
tuxling
Think you have something to bring to the team? then contact me and we shall talk
What is this all about?/Why put this on my device?
This projects aim is to bring a range of linux distros to your android device through a method known as 'chroot', see it has running a linux distro within a virtual machine on your phone. You can access this virtual machine and run it on your phone without causing any damage to your device, or having to overwrite anything. Why might you want this? well my apps are designed to make the install and set up process as easy as possible (more so in the paid apps) while still giving you some flexibility. Once you have the distro up and running then you can pretty much run and install any linux software you like (so long as there is a arm port or it is not architecturaly depenedent), sure there a very few big benefits over what android itself can do but it is still pretty dam cool. (and with the free ubuntu version, hey its free does it matter how useful you find it?)
Wait this uses VNC why shouldn't I just VNC to a computer?
VNC is used to access the GUI as at the moment I have not yet implemented a native way of viewing the GUI. But the Linux distro itself is running within the phone and can be controlled via the terminal app so if your a seasoned Linux user you may never even want to use the GUI
What is Chroot?/How does this work?
"A chroot on Unix operating systems is an operation that changes the apparent root directory for the current running process and its children" - http://en.wikipedia.org/wiki/Chroot
This method of running linux distros with android has been around for some time. I have worked on my scripts to make the process more user friendly and give you far more options from the word go.
The scripts start by mounting the ubuntu image file within the android file system and then mounts the sdcard and if ou have it internal memory within the ubuntu file system.
Chroot is then used to change the root directory to that of the mounted ubuntu and a bash shell is then opened to allow you to control Ubuntu this is kind of like 'booting' the OS.
The likes of VNC and SSHD are then set up when ubuntu is 'booted' to allow you to connect to the GUI if you require it.
Interested?
Ok so you want to get one of the support linux distros on your device, great welcome to the team
But first you will need to find out if your device is compatible with the method before anything else, this method 'should' work with pretty much any device but some ROM's/kernels will not work as they do not have loop device support etc.
HERE is a list of working devices and ROM's/kernels but remember just because its not on the list simply means no one has told me its working, it could still work!
Free Apps/Files
There is now one free app called the Complete Linux Installer (NEW) which can be downloaded from the market, along with the image files.
Complete Linux Installer (NEW)
App [MARKET] [SOURCEFORGE]
Ubuntu 12.04 v4 Core [SOURCEFORGE] [TORRENT FILE] (just the basic install of ubuntu no GUI about 200MB to download and 750MB once extracted)
Ubuntu 12.04 v4 Small [SOURCEFORGE] [TORRENT FILE] (Includes the LXDE desktop about 400MB to download and 2GB once extracted giving about 1GB free space and includes normal programs like firefox)*
Ubuntu 12.04 v4 Full *[SOURCEFORGE] [TORRENT FILE] (The image you have been waiting for including Unity! plus a range of programs this is 1.3GB to download and 3.5GB once extracted with about 1.5GB free space)
Backtrack V8 Image *[SOURCEFORGE] *[TORRENT FILE]
Debian Core v4 *[SOURCEFORGE] [TORRENT FILE]
Debian Small v4 [SOURCEFORGE] [TORRENT FILE]
Debian Large v4 [SOURCEFORGE] [TORRENT FILE]
Paid Apps*
The paid apps are donation keys which unlock the extra features in the Complete Linux Installer (NEW), all the keys are the same but different prices to let you decide how much to 'donate'
Complete Linux Installer Donate £4 [MARKET]
Complete Linux Installer Donate £2 [MARKET]
Complete Linux Installer Donate £1 [MARKET]
Or if you donate more than £1 via paypal I shall send you a custom Donate key to unlock the extra features (if you donate more than £5 you will be added to the contribution list here and on the blog)
You can donate via paypal HERE
Once you have downloaded and installed the app just read through the install guide and soon you should have a complete linux distro running within your android device!
Something not working?
If you can't get it to run please post in this thread your device/ROM/kernel and what app/distro you are trying to use. Please also post a screen shoot of what the terminal app prints out when it try's to boot so we can help debug whats gone wrong

Yes both do support installing new programs, but you have to remember this is a ARM image therefore normal programs for 32bit or 64bit computers will not work, you have to make sure you get a problem build for the ARM processor, if you use apt-get than the sources used all point to ARM ported repository's (in the case of debian this is merged into there normal repository anyway) therefore if you can install it from there you know it will work

I may try this. Looks interesting.

Does Audio work on this?
I.e. can you play audio from the Ubuntu Virtual Machine?
Would you maybe need a special version of VNC that supports Audio or do you possibly have another mechanism?

sadly audio dosnt work, really the last thing to get sorted because yes VNC does not support audio, there are some methods to stream audio but getting it working on android is another story

Thanks for the app. For me, all I want is a full featured linux server (I don't need any GUI). So I tried to install the ubuntu small image, and disabled the dbus / vnc server in the ubuntu.sh script, just trying to play around in the terminal.
Some problems I found:
1) Missing /dev/random , /dev/urandom, which causing sshd fails to start.
2) /dev/null is not a character device.
So I fixed both above:
Code:
rm /dev/null
mknod /dev/null c 1 3
chmod a+rw /dev/null
mknod /dev/random c 1 9
mknod /dev/urandom c 1 9
After installing apache2, and try to start it, it fails to start. From /var/log/apache2/error.log:
Code:
[Sat Apr 07 13:03:15 2012] [warn] pid file /var/run/apache2.pid overwritten -- Unclean shutdown of previous Apache run?
[Sat Apr 07 13:03:15 2012] [emerg] (38)Function not implemented: Couldn't create accept lock
Also, try to ssh to localhost (I confirmed sshd now running locally by checking with netstat -pan) or ssh to any other host, got this error:
Code:
[email protected]:~# ssh [email protected]
Host key verification failed.
Also, when trying to ssh from another computer to that linux instance in the same wifi network, I got the following error:
Code:
imac:~ user1$ ssh [email protected]
[email protected]'s password:
PTY allocation request failed on channel 0
Please help.
Thanks.

Hmmm this are not problems I have run into before, your best bet is to check forums for debian etc, this problems are likely not limited to my builds.
Out of interested what do you plan to use the server for?
You could try the debian core image there is no GUI included so it might be a more stable base to work from

OK I tried the debian small image. Seems better, but still having the same issue with apache2 starting (tried with both worker and prefork packages, both having similar errors):
Code:
[emerg] (38)Function not implemented: Couldn't create accept lock (/var/lock/apache2/accept.lock.4882) (5)
Sounds like something missing in the linux kernel.
May be that sounds crazy, but I want to have a linux based LAMP server running in galaxy tab (8.9) for web development. Oh yes, I also got a galaxy note, that's why I see this thread.

That' the dumbest comment I've seen today realizing that Android and iOS (+80% of the smartphone market today) are both sort of Linux (/UNIX based) distros.

Good idea, but yes looks like it could be, my method shares the android kernel it donst have its own kernel so this could be the problem, might have to talk with your kernel devs?

Well yes A android is a form of linux, and in fact I believe as of linux kernel 3.3 android is being merged into the main kernel.
But anyway the use of having a full linux distro? well why not? you could run the likes of open office, a real web browser and a whole range of other programs you cant in android
