A fix should have been released in 23.08.2 (https://invent.kde.org/pim/merkuro/-/issues/227 but I'm afraid on my neon-user system that is not the case.

Comment 2 PK 2023-10-17 05:14:08 UTC

On this page https://invent.kde.org/pim/merkuro/-/issues/227 there is a "walkthough" about how you can still create a google account in Merkuro calendar:
cd into .config/akonadi
     nano or vim into file agent_config_akonadi_google_resource_X
     With Name entry do this:
     Name=youremailaddress@gmail.com
     and save the file.
     restart calendar settings or better still akonadictl restart and then close terminal
     you should be good to go
Only the leaps he makes are just a little too big.

At last I found out the way to do it. I reproduced it and it works:
     start merkuro calendar
     from the menu choose Settings/create merkuro calendar
     now the account-setup main screen opens
     in the account-setup main screen choose to create google account
     now the google account sub-window opens
     perform what you have to do (in browser etc)  and close browser
     now the google account sub-window looks quite all right
     - important - open Dolphin and browse to the file ~/.config/ agent_config_akonadi_google_resource_X
     put your gmail address behind "Name="
     save the file and close it
     - important - now apply all in the google account sub-window and close it
     - important - but DO NOT CLOSE THE ACCOUNT-SETUP MAIN SCREEN (this will clear all you just did)
     keeping merkuro as it is, open the konsole and give command "akonadictl restart"
     now the google-stuf appears in the left side of the merkuro calendar application
     NOW it is really done.
Btw, while figuring this out I had to clear the google calendar setting a few times in the account-setup main screen. This made my system freeze totally. Quite spectacular.
