Need help with Regression Potential section. I have no idea about possible regressions.
According to https://wiki.ubuntu.com/SecurityTeam/UpdatePreparation#Update_the_packaging if you want to fix it in 18.04 you should patch latest version for 18.04 (3.5.1-1ubuntu3) so this is updated debdiff for Bionic applicable to 3.5.1-1ubuntu3. It builds successfully, the patch works as intended. ** Description changed: + IMAP connection to imap.gmail.com over SSL returns self-signed + certificate. Though you can still connect to imap.gmail.com using this + certificate, it would be better to fix it to avoid this scary warning + (self-signed certificate) and provide a smoother user experience. + + Test Case + Install sylpheed. Start sylpheed. Create IMAP account for gmail.com in sylpheed (IMAP4 (Gmail)). Check for new email. You should get a warning complaining about self-signed certificate. + With fixed package, try the same. This time you should not get the warning. + + Original Description + -------------------- Problem appeared after upgrading from Ubuntu 18.04 to 18.10. When starting Sylpheed, connecting to imap.gmail.com over SSL, I get a warning embedded in the SSL certificate: "Subject: /OU=No SNI provided; please fix your client./CN=invalid2.invalid " May be related to this bug report about 'fetchmail' in redhat enterprise when it was still using TLSv1.2 instead of TLSv1.3: https://bugzilla.redhat.com/show_bug.cgi?id=1611815 https://gitlab.com/fetchmail/fetchmail/commit/9b8b634312f169fab872f3580c2febe5af031615 ProblemType: Bug DistroRelease: Ubuntu 18.10 Package: sylpheed 3.5.1-1ubuntu3 ProcVersionSignature: Ubuntu 4.18.0-10.11-generic 4.18.12 Uname: Linux 4.18.0-10-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.10-0ubuntu13 Architecture: amd64 CurrentDesktop: XFCE Date: Tue Oct 23 00:27:01 2018 InstallationDate: Installed on 2016-06-05 (869 days ago) InstallationMedia: Xubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) SourcePackage: sylpheed UpgradeStatus: Upgraded to cosmic on 2018-10-21 (1 days ago) modified.conffile..etc.default.apport: [modified] mtime.conffile..etc.default.apport: 2018-03-20T22:16:27.108498 ** Tags added: bionic ** Patch added: "1-3.5.1-1ubuntu3.18.04.1.debdiff" https://bugs.launchpad.net/ubuntu/+source/sylpheed/+bug/1799345/+attachment/5292251/+files/1-3.5.1-1ubuntu3.18.04.1.debdiff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799345 Title: Sypheed not (or no longer) using SNI for SSL connections To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sylpheed/+bug/1799345/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
