Multiple apps fail to launch from Ubuntu 17.10. When I click on some of the apps they do not launch.

i tried doing

sudo apt install unity
unity --reset-icons

when i open a application for example steam), this comes up

tar: This does not look like a tar archive
xz: (stdin): File format not recognized
tar: Child returned status 1
tar: Error is not recoverable: exiting now
find: ‘/home/jitu/.steam/ubuntu12_32/steam-runtime’: No such file or directory
