Status in gnome-software package in Ubuntu: Triaged Status in snapd package in Ubuntu: New Bug description: [Impact] When viewing information about installed snaps they all show their size as "Calculating...". This is because snapd is not providing any size information for installed snaps. [Test Case] 1. Start GNOME Software 2. Select a snap that is installed (e.g. moon-buggy) 3. Check details section Exepected result: Section shows appropriate size of snap Observed result: Section shows "Calculating..." for the size. It is never calculated. [Regression potential] Low, the solution is to populate the field.
