Hi Nathan, Thanks for the suggestions. It does look like clicking on the Additional Drivers tab is common to almost every instance where this issue occurs but it doesn't always trigger the issue. For every test where i only click on the Updates tab and no other tabs, I don't see the issue. In two cases, the not responding message occured before I had even finished typing in my password to the authentication box.
I did look into the following messages which occur in all tests (regardless of pass {no issue} or fail): Mar 26 22:58:19 t14s polkitd[1511]: Identity `unix-group:admin' is not valid, ignoring: No UNIX group with name admin: No such file or directory Mar 26 22:58:24 t14s polkitd[1511]: Operator of unix-session:2 successfully authenticated as unix-user:aaron to gain TEMPORARY authorization for action com.ubuntu.softwareproperties.applychanges for system-bus-name::1.315 [/usr/bin/python3 /usr/bin/software-properties-gtk] (owned by unix-user:aaron) The first message seems to relate to bug: https://bugs.launchpad.net/ubuntu/+source/policykit-1/+bug/2084151 I can also confirm that modifying /usr/share/polkit-1/rules.d/ubuntu-admin.rules to group adm from admin and rebooting, I no longer see the 1st message but the reported issue in this bug report still remains. In subsequent tests, I get the following, regardless of whether I see the reported issue or not: Mar 27 10:17:47 t14s gnome-shell[3731]: polkitAuthenticationAgent: Received 3 identities that can be used for authentication. Only considering one. Mar 27 10:17:51 t14s polkitd[1460]: Operator of unix-session:2 successfully authenticated as unix-user:aaron to gain TEMPORARY authorization for action com.ubuntu.softwareproperties.applychanges for system-bus-name::1.282 [/usr/bin/python3 /usr/bin/software-properties-gtk] (owned by unix-user:aaron) There seems to be some inconsistency and I can't see anything obvious. Perhaps you will see something of interest from the attached logs or please let me know if you need something else. ** Attachment added: "tests and log messages.txt" https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/2104209/+attachment/5867625/+files/tests%20and%20log%20messages.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2104209 Title: Applying changes to the value of "Notify me of a new Ubuntu Version" causes timeout message "Software & Updates Is Not Responding" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/2104209/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
