Here are my checks:

Therefore, the previous signing key signed the new key, establishing the chain of trust. In summary, given that: a) the key that signed the 6.10 release tarball is present in https://www.squid-cache.org/pgp.asc b) the key that signed the 6.10 release tarball was signed by the previous key we have in d/u/signing-key.asc I conclude that this is enough to add the new signing key to d/u/signing-key.asc, and validate the 6.10 tarball. Could you please file a PR in salsa with this reasoning, if you agree with it of course, updating the key? Let's see if they act on it today or tomorrow. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2073322 Title: Upstream microrelease 6.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/squid/+bug/2073322/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
