@Otus, many thanks for verifying on Xenial. The SRU verification process [1] now requires to provide a brief description of how the bug fix was verified. Would you be so kind to do it, please? I generally give the "dpkg -l | grep tor" output to confirm the right package version was tested and mention that I successfully went through the reproduction steps as outlined in the bug description. If you get a chance to test on Artful that would be nice otherwise I'll try to do it myself as time permits. 1: https://wiki.ubuntu.com/StableReleaseUpdates#Verification -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1731698 Title: [SRU] Tor 0.2.9.14 and 0.3.0.13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tor/+bug/1731698/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello Simon, or anyone else affected, Accepted tor into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/tor/0.2.9.14-1ubuntu1~16.04.1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .
