Hi when upgrading from Ubuntu Jammy upto Ubuntu Noble, I had this message :
Continue [yN] y Get:1 Upgrade tool signature [833 B] Get:2 Upgrade tool [1267 kB] Fetched 1268 kB in 0s (0 B/s) authenticate 'noble.tar.gz' against 'noble.tar.gz.gpg' Authentication failed Authenticating the upgrade failed. There may be a problem with the network or with the server. I had to connect to the APT-Cacher-NG server and do this to solve my problem : sudo find /var/cache/apt-cacher-ng -name 'noble.tar.gz*' -delete sudo systemctl restart apt-cacher-ng Hope this can also help others. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/156070 Title: "Failed Upgrade tool signature" when using do-release-upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt-cacher/+bug/156070/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
