Hi,

I sort of start feeling old, trying to participate in UBports: An open source project without a mailing list and without IRC channel does not really integrate with the modes of communication I'm used to use.

Just tried to make a telegram account (via web.telegram.org), however it needs a phone number, and (one of my) "landline" SIP-based phone numbers is not accepted ("incorrect phone number"). I'm not really willing to give my cell phone number to an untrusted 3rd party to participate in an open-source project. I mean, if I were, then I probably would just be using Google Android and not bothering with UBports, would I :) ?

So I guess I'll have to stay at the outside for now.

cheers,

Dave

So this is where my flash memory is going:

$ mount|grep mmcblk0p23 | sed -n -e 's/.*on \([^ ]\+\).*/\1/p'|sudo xargs du --max-depth=2 -c -h

-> /userdata/system.img is taking 2 GB and seems to be the actual ubuntu touch file system image. Then I wonder why there is another 4 GB partition in /dev/mmcblk0p21. This is mounted on /android/cache. Is there any reason for that "cache" partition taking up so much memory? Can its size be changed during installation from the ubports-installer to leave more room for my home partition?

@advocatux my profile was still empty by the time you wrote your reply. sorry for wasting your time :)

Just to document some findings, in case somebody is looking for the same answer: This is how I am using and "integrating" normal Ubuntu and other 3rd-party applications into the launcher:

Creating a libertine image, as documented here.
Example:

libertine-container-manager create -i legacy -n "Legacy"
libertine-container-manager install-package -i legacy -p gnome-terminal
libertine-container-manager install-package -i legacy -p openjdk-8-jre

Now from the OpenStore install package "Desktop Apps". Enable the "Desktop Apps" scope in the launcher. Now swiping left on the Launcher should bring up the "Desktop Apps" scope. After running the commands above it lists just two items: "OpenJDK Java 8 Policy Tool" and "Terminal" . To add other custom launchers (for example to launch some manually installed Java GUI application), you can add more items to the Desktop Apps by creating files inside the libertine container at /usr/share/applications/*.desktop.

Example:

libertine-container-manager install-package -i legacy -p joe
libertine-container-manager install-package -i legacy -p vim
libertine-launch -i legacy  /bin/bash
cp /usr/share/applictions/terminal.desktop /usr/share/applictions/myapp.desktop
joe /usr/share/applications/myapp.desktop

For example to launch a java application installed in /home/phablet/.local/share/libertine-container/user-data/legacy/myapp.jar , edit myapp.desktop and change the line

Exec=/usr/bin/java -jar /home/phablet/myapp.jar

(Note how the container's directory /home/phablet corresponds to the absolute path /home/phablet/.local/share/libertine-container/user-data/legacy/myapp.jar when accessed outside the container)

@advocatux,

thanks for the reply. I sort of understand and expect slight differences between df and du output. However, here it's like a factor two difference.

Digging a little deeper, I think the reason may be the strange file system / mountpoint layout used by ubuntu touch.

mount | grep /dev/mmcblk0p23

Lists more than 40 directories that are mounted via device /dev/mmcblk0p23. Looking at /etc/fstab this seems to be accomplished via some bind-mount trickery. However the "actual" directory corresponding to /dev/mmcblk0p23 seems to have been unmounted after bind-mounting, so there is no easy way to find out which directories outside /home take up the "lost" gigabyte of memory.

Looks like after some tinkering with libertine, I'm soon going to be out of memory :)

cheers,

Dave

Hi,

sorry for posting yet another (possibly stupid) question:

"df /home" shows that I consumed 2.7 GB of memory, whereas "du -h /home" only shows about 800 MB of used memory. Is that normal? Any way to reclaim those lost 2 GB of memory?

phablet@ubuntu-phablet:~$ sudo df /home -h 
Filesystem                       Size  Used Avail Use% Mounted on
/dev/disk/by-partlabel/userdata  9,3G  2,7G  6,7G  29% /home

phablet@ubuntu-phablet:~$ sudo du -h -c --max-depth=0 /home 
798M	/home
798M	total

cheers,

Dave

Hi,

just started playing around with libertine, following the information provided here.

Now wondering why libertine-container-manager does not have any option to specify the directory where the container is created. I'd like to put it onto the micro-SD card.

Will there be any complications if I move the container over to micro-SD and replace it with a symbolic link?

With all the install activity that "libertine-container-manager create" is causing I'm sort of afraid, that otherwise I'll wear out the internal flash over time.

Hi,

just to give some more data point: ordered a BQ M10 FHD Ubuntu Edition tablet, arrived yesterday. Installed ubports-installer on a Ubuntu 17.10 linux PC. Tablet initially not detected by the installer, but after setting developer mode, some reboots, trying a different USB port, and manually running "adb" to list connected devices, it "suddenly" started working (hat no prior experience with adb, never used it before).

After detection, installation just completed flawlessly (I configured it to wipe the tablet during installation).

So for now very happy with the device and the software. Next step will be to install some ubuntu desktop applications using the information found here:

https://docs.ubports.com/en/latest/userguide/dailyuse/libertine.html

Anybody here knows which libertine container types are supported by ubuntu 15.04r3 on BQ M10 FHD?

Looking forward to replacing my aging firefox-os phone with some new phone running ubports.

cheers,

Dave
