It looks like the servers listed in the bug description require SIGN- RSA-SHA384, which gnutls26 doesn't support.
The issue can be reproduced with gnutls28 by disabling the additional signature algorithms: gnutls-cli --priority "NORMAL:-SIGN-ECDSA-SHA256:-SIGN-RSA-SHA384:-SIGN- ECDSA-SHA384:-SIGN-RSA-SHA512:-SIGN-ECDSA-SHA512:-SIGN-RSA-SHA224:-SIGN- DSA-SHA224:-SIGN-ECDSA-SHA224:-SIGN-ECDSA-SHA1" -d 256 sequencewiz.com Fixing this likely requires at least the following commit to be backported: https://gitlab.com/gnutls/gnutls/commit/75b493132239e824d671f4b09d1dfd0f7ca6a8b1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1444656 Title: GnuTLS TLS 1.2 handshake failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnutls26/+bug/1444656/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
