The output of snap interfaces indicates that wekan does not plug hardware-observe. If it did, you would see this in snap interfaces:
$ snap interfaces Slot Plug ... :hardware-observe - ... - wekan:hardware-observe ... See 'snap connect --help' for information on the syntax. *If* wekan plugged hardware-observe, the syntax would be: $ snap connect wekan:hardware-observe -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1744718 Title: Install/refresh stuck at configure hook (Wekan) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1744718/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
