I believe I have solved my own problem.

I did not have a full libertine install done (no write access to the tablet) so chances are a lot of per-requisites were missing. I think OTR can handle libertine containers in addition to the other stuff that it does, but more was missing.

Doing the following below, I was able to successfully install DOSBox on my BQ tablet. Couple of catches is from what little I have tested it can be sluggish (especially when multitasking with a background terminal session (from my computer), and the sound does have some remnants (distortion post making sound if that makes any sense). I was also able to mount my home directory (mount ~/Downloads/dosbox) and copy over my apps and games with no problem. I have only tested this with a bluetooth keyboard. There may be a much better way of doing this, however I have yet to see any info on doing this. I principally wanted to play some old dos games (and wordperfect lol).

Steps to install DOSBox on Ubuntu Touch

Computer Side

I had magic-device-tool installed (for Phablet-tools and other pre-requisites)

Ubuntu Touch Side

1. Enable read-write access to install libertine support (this will reboot tablet)
   phablet-config writable-image

2. Install Libertine Software
   apt-get install libertine libertine-scope xmir python3-libertine-chroot

3. Create libertine DOSBox container
   libertine-container-manager create -i dosbox -t chroot

4. Install DOSBox in libertine container
   libertine-container-manager install-package -i dosbox -p dosbox

5. Configure DOSBox preferences
   nano /home/phablet/.local/share/libertine-container/user-data/.dosbox/dosbox-0.74.conf

I changed the following settings (all under SDL)

fullscreen=true
fulldouble=true
fullresolution=1920x1080
output=overlay

• Setting the full screen resolution to the max (1920x1200) caused DOSBox to crash. I chose 1920x1080 to get the most coverage on screen (this can obviously be tweaked)

Let me preface that this has no practical purpose and is more of a side project (fun in a odd sense).

Recently there was a collection of old Ubuntu images from canonical that were published to archive.org (includes from cdimage.ubuntu.com along with a cache from ubuntu-emulator).

I thought it would be interesting from a historical perspective (dare I say this one day would be considered retro in the computing sense ) getting a Xenial virtualbox instance configured complete with Ubuntu SDK, along with the built-in emulation etc... The idea would be if someone wanted to play with compiling clicks, seeing the os through its development etc prior to canonical cancelling it with or without physical hardware (knowing nexus based devices may eventually be completely irreparable).

I found on the forum that there once was an Ubuntu touch programming course that a user created that did have vm uploaded to google drive however we are talking years ago and through the course of time the link is now 404.

Additionally I have been looking to potentially building the full VM myself which the issue then becomes the actual SDK images since the sdk.cannonical site has passed to the ether. I have been looking into the usdk-image-tools on ubports github and was successful on the xenial images. However on the vivid images (after changing the repos to old-releases etc...) it is failing on a SSL error when attempting the PPA which I think can be getting around by recoding the ppa to the archive url and append it to the sources.list.

I guess my question is in three parts (obviously if the top point is answered the others are irrelevant).

• Does anyone have a VM of a functional Ubuntu SDK environment that would be willing to share?
• Is there any available Ubuntu SDK images for Vivid floating out there?
• I know how to import LXD containers in general however when I attempted the 16.04 images i created Ubuntu SDK did not see them, rather wanted to go to the *.cannonical.com. Am I missing an alias or something special that made that seen on the backend?

I will check the logs and try to get some more information later today (work ATM).

Please forgive me if this is the wrong forum for this. On OTA-15 (BQ M10FHD) I am running OTR (On The Road) which appears to simply be a front-end for Liberatine. Thus far I have been able to create containers and use apt-get to install applications (both X11 based and command line). However when I attempt to install DosBox, when i execute from the command line a garbled screen appears and I have to forcibly reboot the tablet. Launching it from the home screen the full screen app launcher appears (black with DOSBOX icon) then immediately closes.

I have seen on YouTube that this has ran at some point on Ubuntu Touch. I am curious if anyone has had any experience with getting this working or any advice (where to find the logs, etc..). Thanks for any help!
