I'm guessing there are some SSL certificates involved? If so, this issue is mentioned in the release notes: certificates that use e.g. SHA1 as the digest algorithm should be re-issued by your provider with a stronger hash algorithm.
Would you be able to check that it is the correct diagnostic? If you have a PEM file, you can see mentions of the hash algorithms in the "Signature Algorithm" fields when using the following command: openssl x509 -in cert.pem -noout -text -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1972939 Title: Jammy tinc incompatibile with older (e.g. Xenial) tinc nodes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1972939/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
