The error is caused by the following line of code https://github.com/Guake/guake/blob/150a3a77f9355cb49e3c45a9be850b2f1ac684ec/guake/guake_app.py#L1473
> self.delete_tab(self.notebook.page_num(widget), kill=False, prompt=False) In the 3.0.5-1 package, this line is indented, causing it to only be executed if libutempter is installed. Upstream has unindented this line so that removal of the tab always occurs whether libutempter is installed or not. Fix is to either unindent this line (line #1420 in the gauke_app.py that ships in 3.0.5-1), as upstream has done, or include libutempter0 as a dependency for the guake package. Anyone who is currently affected by this bug can mitigate it with `apt install libutempter0`. Here's the original issue in upstream's ticket tracker (that was unhelpfully not linked in original reporter's ticket): https://github.com/Guake/guake/issues/1198 ** Bug watch added: github.com/Guake/guake/issues #1198 https://github.com/Guake/guake/issues/1198 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767639 Title: Ubuntu 18.04: FileNotFoundError: [Errno 2] No such file or directory: '/proc/4106/cwd' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/guake/+bug/1767639/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
