Get that issue after having changing "trusty" to "utopic" inside /etc/apt/sources.list In factthat trouble is often met with a new release cycle :
/usr/share/python-apt/templates/Ubuntu.info is simply not aware of "utopic"; Ubuntu.info needs to be upgraded with the whole "utopic" blocks, after the "devel" blocks and before the "trusty" blocks. So that also means that "devel" ignore "utopic" right now. As a result, synaptic -> repositories cant be opened to set our preferences. Changing "utopic" by "devel" inside sources.list does not allow synaptic to open the "repositories" to select what we wanting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1312673 Title: software-properties-gtk crashed with aptsources.distro.NoDistroTemplateException in get_sources(): Error: could not find a distribution template for Ubuntu/utopic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1312673/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
