Can someone who’s run into this problem test rebuilding just the ssu cache instead of adding the missing repo manually? There’s a bug in ssu that we didn’t think affected public releases, but this is sounding very similar.
Remove any Jolla repos (from the section of user added repos) you might have added manually with:
ssu rr <repo name>
then do:
devel-su
rm -r /var/cache/ssu/
ssu ur
After this, you should see the missing repo (e.g. adaptation-common) in the system repos when you run ssu lr. Please let me know if this gives you the correct repository listing, and if so then i’d recommend doing that rather than adding the repos manually, as this might break the next upgrade if that repo can’t be updated to the new version.
