As supposed in Question #129493 the reason for this issue could be that the Austrian mirror currently isn't up-to-date as you can see. So I looked at this mirror list (https://launchpad.net/ubuntu/+archivemirrors) and changed my sources.list (I'll attach this file) to use the Georgian mirror - which also isn't up-to-date right now (status: one week behind). But I couldn't reproduce this bug.
I tried four different mirrors and the only one with which I can always reproduce this bug is the Austrian country mirror. ** Attachment added: "sources.list (Georgia)" https://bugs.launchpad.net/ubuntu/+source/apt-p2p/+bug/667313/+attachment/1715198/+files/sources.list -- Software authentication issue: apt-p2p & offical country mirror for Austria https://bugs.launchpad.net/bugs/667313 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
