On Gramps for Genealogists, Dianne Reuby posts:
After 20 years using Gramps on Ubuntu, I still find upgrades challenging! I can do a full backup with no problems, and the App Center had version 6 available. It seemed to install OK, but after install the “open” option is greyed out - I can only uninstall.
Should I have uninstalled version 5 before installing 6?
In the App Center, once installed there’s a drop-down with various choices according to the app. On Gramps you can have open (greyed out) or uninstall. This is from the snap version, I think.
The problem was due to lack of permissions to access DBus. I had to create a slot as recommended in the Snapcraft documentation, but unfortunately my latest upload now requires a manual human review.
I’ll keep you updated and chase the progress tomorrow if necessary.
I’m not sure why my original Snap works on Arch Linux, but not Ubuntu.
