Description dofficialgman 2024-11-13 21:20:24 UTC 
SUMMARY
The system failed to update due to a new dependency that got automatically installed but cannot be configured due to conflicts. This is because of the `ktnef` package (from ubuntu) that depends on libkf5calendarcore5abi2 which conflicts with the new neon package libkf5calendarcore5 due to shared files
