After updating to frameworks 5.76, various akonadi resources and agents aren't working properly (e.g. the IMAP resource). They are offline or in state "trying to connect". It seems to be related to networkd. The issue doesn't occur if network-manager is used.
STEPS TO REPRODUCE
1. Use networkd instead of network-manager
2. Update to frameworks 5.76
3. Run kontact
Various resources like the imap resource are offline
The resources are online
Linux/KDE Plasma: KDE neon 5.20 (Ubuntu 20.04)
(available in About System)
KDE Plasma Version: 5.20.3
KDE Frameworks Version: 5.76.0
Qt Version: 5.15.1
Downgrading to frameworks 5.75 doesn't fix this issue. So an other update seems to be responsible for this bug. Has anyone any idea?
I can confirm this is still an issue in Plasma 5.22.5 and Frameworks 5.86.
