How to manually upgrade from OTA-3 to OTA-4
@mihael the correct command is
sudo system-image-cli -vvvv --switch 16.04/stable
-vvvvparameter is just in case you want a verbose output in your terminal, so you can skip it.
See http://manpages.ubuntu.com/manpages/xenial/man1/system-image-cli.1.html if you want to use other parameters. For example, if you want to wipe your device too.
You can run that command directly in your phone or entering in your phone from your computer using

@advocatux Great! Thanks! I'll try that... I put
ubports-touch/16.04/stableand not only
16.04/stablebecause that was what I found among the channels that I got from running
sudo system-image-cli --list-channels...
@mihael the command I posted is tested and I know it works. Yours should work too but I preferred to post the proven method
This command doesn't work for me. This is the message:
Exception occurred during update; see log file for details.

I have made this in paste.ubuntu. I don't know if it's correct.
Really is a big error message...
@llamasjm what is the exact UT version running in your phone?

To be clear, redirection of 15.04/rc and devel to 16.04 does not start until next Monday, the 3rd. Until then, switching channels like that will not upgrade you to 16.04
Does this apply to all Ubuntu Touch devices, such as my OTO, or is this release on the 3rd for specific devices?
@isolated-thinker Yes this should cover all devices on OTA-3(15.04).
All clear. I'm on OTA-3. Well, tomorrow I'll be at home, with my Ubuntu computer, and using UBports installer OTA-4 will be here without problem, for sure. Thanks!
Hi everyone, I have a BQ Aquaris E5 with UBPorts OTA3, will I loose SMS, calls history and contacts if I upgrade to OTA4 ? Thanks.
@mika15 it's always a good idea to make a backup but said that, you'll keep all your data if you don't check the
@advocatux Thanks for the quick response! I will do a backup before upgrading using rsync over ssh is enough as it or some procedures are better ? Other question, If I'm not happy with OTA4, is easy to downgrade or do I have to forget ? Thanks!

@mika15 you're welcome. You can backup the whole
/homeif you want peace of mind [*] but you only need to backup the data you want to keep really.
You have the obvious things like Documents, Music, etc, that's easy to find
~.local/share/evolution/you'll find the addressbook, calendar, memos, and tasks DDBB.
~.local/share/history-service/history.sqlitefor SMS and calls log.
If you're using Authenticator, you'll find the config file here
Probably the easier way to downgrade is to use the installer, probably switching channels will work too though.
[*] Edit to explain that if you have a complete home backup, you can easily copy to your phone any bit you could need or you forgot the first time
Thanks for this, @UniSuperBox
How long does the download take? I'm just wondering if the Snap is hanging, or whether! it's doing its thing.
@3arn0wl How long is long? About 15-20 mins all should be done.
Meh! It was longer than that, I think. I might just wait for OTA-5.
@3arn0wl Just restarting the installer and reconneting the phone fixed it for me when installing ubports on the nexus. Try that if you cant wait till Monday ; )
I also ran into the installation hanging after clicking "Install," even with the latest version (0.1.21-beta AppImage) of the installer. I discovered the problem, in this case at least, concerned the installer's handling of adb and fastboot. The system is intended to operate whether they are installed or not. I had adb installed, but not fastboot. Unfortunately, the fallback appears to have failed because the "platform-tools" subdirectory tree it depends on (see src/utils.js:getFallbackPlatformTools) is missing. However, once I installed fastboot, the installation did not need to fall back and it worked just fine.
@advocatux Thanks! Migration is done, my phone is working perfectly, I migrated from AppImage installer a fantastic tool, I have all my data as it was before, many thanks to the team for their work, the installer and the OS are excellent!
