Hello Till, or anyone else affected, Accepted system-config-printer into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source /system-config-printer/1.4.3+20140219-0ubuntu2.4 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 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 to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

Hello Till, or anyone else affected, Accepted system-config-printer into utopic-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source /system-config-printer/1.5.1+20141010-0ubuntu2.2 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 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 to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

The problem occurs on Trusty, Utopic, and Vivid. Added a task for system-config-printer for using python-requests instead of pycurl as a workaround. Note that this does not fix the problem of pycurl. ** Changed in: system-config-printer (Ubuntu Trusty) Status: New = Triaged ** Changed in: system-config-printer (Ubuntu Utopic) Status: New = Triaged ** Changed in: system-config-printer (Ubuntu Trusty) Importance: Undecided = High ** Changed in: system-config-printer (Ubuntu Utopic) Importance: Undecided = High ** Changed in: pycurl (Ubuntu Utopic) Importance: Undecided = High ** Changed in: pycurl (Ubuntu Trusty) Importance: Undecided = High ** Changed in: pycurl (Ubuntu) Importance: Undecided = High -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pycurl in Ubuntu. https://bugs.launchpad.net/bugs/1394244 Title: pycurl gives 'gnutls_handshake() warning: The server name sent was not recognized', curl on command line and wget work with same URL Status in pycurl package in Ubuntu: New Status in system-config-printer package in Ubuntu: Fix Released Status in pycurl source package in Trusty: New Status in system-config-printer source package in Trusty: Triaged Status in pycurl source package in Utopic: New Status in system-config-printer source package in Utopic: Triaged Bug description: From a Python program (system-config-printer) I need to access an https URL (on OpenPrinting) assuring that the answer really comes from OpenPrinting and not from an attacker.
