I try to clean yum cache several times but it doesn’t changed anything.
What could i do?
Please try exclude/disable the repo on command line as a workaround:
yum --disablerepo=mrmarkuz update ...
EDIT:
I think I could reproduce the error. The repo needs to import keys and it’s not done automatically in Software Center (fully ok, it’s about security). So if you just install the repo and go immediately to Software Center it may not work.
Please do the update once on command line:
yum update
This way you should be asked for importing the repo keys.
I think about importing the keys at repo install now to avoid this. Thanks for pointing out.
