I have the same problem trying to back up my system using Deja Dup. When I try to run the app, I first get a message that I need to install package gvfs-backends
When I try to install the package, I get 'Error while installing package: installed python3 package post-installation script subprocess returned error exit status 4. Then, Deja Dup turns itself off. I cannot back up my system with it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to hplip in Ubuntu. https://bugs.launchpad.net/bugs/1766020 Title: package python3 3.6.5-3 failed to install/upgrade: installed python3 package post-installation script subprocess returned error exit status 4 Status in HPLIP: In Progress Status in hplip package in Ubuntu: Confirmed Bug description: Hello, error came up while updating.
