Upgrade Nexus 4 from UT 15.04 OTA 14 to latest 16.04
I have a Nexus 4 that I flashed in 2016 to UT 15.04 OTA 14.
When Canonical dropped the project I put the phone away in a drawer.
Now that thanks to UBports the project is picking speed again, I'd like to update to latest version.
Unfortunately, the "update" buttons in my 15.04 versions says I have the latest version. Impossible to upgrade.
From what I've read, the UBports installer works to install UT from an Android phone, not from a previous UT release, and might render my phone useless.
Anyone knows how I can safely upgrade this phone?
I may add that running "system-image-cli -vvvv" on the command line returns several FileNotFound python Exception, about the following file:
Any idea if this is related (I guess so) and how I can solve this issue?

Will it work? Doesn't UBports installer require an Android OS (on the phone)?

@vmotion no, the installer works great on a UT phone
Edit: of course you can
adbto your phone (remember: developer mode on) or open the Terminal in your phone, and run
sudo system-image-cli -vvvv --switch 16.04/stabletoo.
It looks like your phone is still pointing at the Canonical system-image server. You will not be able to upgrade or switch channels until you use the UBports Installer to move to a build of Ubuntu Touch from UBports.
