--- Comment #1 from Benjamin <benjami...@gmx.at> --- Okay I tried to debug the problems...I found a working solution (seems to work will see for the future) ...Reinstalled the flatpak at flathub: sudo flatpak install flathub org.kde.kontact Then there seems to be a bug which is described here: https://syve.wordpress.com/2020/05/24/akonadi-bug-qlocalsocketconnecttoserver-invalid-name/ I just did remove the databases with: akonadictl stop mv $HOME/.local/share/akonadi/db_data $HOME/.local/share/akonadi/db_data_old Attention because this removes all the data and calendars! So better backup before if you are unsure. and then readded the calendars and everything seems to work...hopefully. -- You are receiving this mail because: You are watching all bug changes.
