UNSOLVED Enabilng webgl
I enabled webgl followingthe commands found in telegram:
These are the Terminal commands I used: sudo ubports-qa install xenial_-_gpu-browser sudo -i mount -o remount,rw / cd /etc/profile.d/ cp disable-qtwebengine-gpu.sh disable-qtwebengine-gpu.old rm disable-qtwebengine-gpu.sh
and it works ok but i'm left with this apt status:

Can this be fixed?

@suoko the problem is that we bind-mount a lot of files, if an update comes across such a file then it cannot be updated. Thats also why apt is only used as an update method in development. In your case its probably Ok to ignore the error though.

@suoko were you on dev channel before using the ubports qa tool?
@mateo_salta I am getting the same and am on the dev channel, so that's not it: https://forums.ubports.com/topic/3188/morph-browser-not-possible-to-show-map-due-to-missing-webgl/9?_=1627584581816 ... Is the ubports-qa command even available on stable/staging? I thought it is not present at all there.
@zubozrout It is but it's usually not recommended to use there especially if devel already has many changes compared to them. So it's safer when closer to an OTA release
