Hmm... it seems that installing the "gnome" metapackage (which is not pulled in via gnome-shell) fixed this issue for me.
Here's my APT log if somebody wants to dig through that to try to determine exactly what the problem is... Also, I've included a line-by- line stylized summary of the installed packages (created from the apt log, but a lot easier to read) Possibly it was gnome-js-common? ** Attachment added: "apt.log" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/990551/+attachment/3448838/+files/apt.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990551 Title: Missing gnome-shell screen recorder To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/990551/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
