I just rebooted my system after an update, and am now receiving library errors trying to run kmail.
akonadi_kolab_resource is owned by kdepim-runtime, but recompiling that package did not resolve the issue.
After some searching, I found that the libkolabxml dependency for kdepim-runtime was the culprit. Recompiling libkolabxml against boost 1.78 resolves the error.
This problem should be fixed by now.
If not pls update this post
