On Bionic it finds ~27 Fedoras and then also plenty of rhel entries. In fact on cosmic there are a few more releases known (newer OSDB). But I think I have spotted what breaks it.
Cosmic: idx 116 osobj.name fedora-unknown idx 117 osobj.name fedora28 idx 118 osobj.name silverblue28 idx 119 osobj.name fedora27 idx 120 osobj.name fedora26 idx 121 osobj.name fedora25 Bionic: idx 36 osobj.name fedora-unknown idx 37 osobj.name fedora26 idx 38 osobj.name fedora25 idx 39 osobj.name fedora24 idx 40 osobj.name fedora23 idx 41 osobj.name fedora22 Those are the full lists and the unsorted silverblue28 in there is odd. The code expects to find a list sorted to only contain fedora* and rhel* entries. It makes sure that the first non-fedora is rhel and that fails. This call fails pref_list = OSDB.list_os(typename="linux", sortpref=["fedora", "rhel"]) Due to the full_list not being ordered correctly in Cosmic. The silverblue28 entrey is clearly not at the "s" place in an alphanumeric sort. That is from: from virtinst import OSDB from virtinst/osdict.py:129 sortpref is defined as :param sortpref: Sort these OSes at the front of the list The sort algorithm uses osinfo.urldistro to "clump" same distros together. /usr/share/osinfo/os/fedoraproject.org/silverblue-28.xml of package osinfo-db lists it as fedora27 derived and that makes it clump with fedora. Works: osinfo-db 0.20180226-1 Fails: osinfo-db 0.20180929-1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1796932 Title: FTBFS in cosmic test_list_os To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virt-manager/+bug/1796932/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
