Hi Stefano,
worked like a charm: thank you very much.
Now it says Ubuntu 15.04(r2) in System settings and the Startscope ist gone (which does not matter).
Kalendar and Apps are all still there, so are my Files, Photos and Music.
Ubuntu has once more shown what a fabulous System it is and Linux has once more shown that Community is worth more than any big Firm or big money.
Two Questions come up now:
- will i get updates of the OS as OTA? or do i install them just like i did now (which would be OK)
- is there now a new "store" built in where i can get updates of the Apps? I only use Kalenda, unav and Telegram
Again: Thanks alot
Holger
