Since 2 weeks I have a problem when updating my Ubuntu Unity 18.04, installed in march with the Ubuntu-Unity iso image dd 2018-02-03 from the Unity maintainers. I get these messages:
“failed to download repository information” and
E: Repository ‘http://ppa.launchpad.net/unity7maintainers/unity7-desktop/ubuntu bionic InRelease’ changed its ‘Label’ value from ‘Ubuntu-Unity-18.04-Testing’ to 'Ubuntu-Unity-18.10-Testing’
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.
I don’t know how to fix this. I am sorry if this is the wrong place for asking support, but I don’t know where else to go since this concerns Unity. I hope you have a solution because I want to stay with Unity forever!
Thank you in advance,
