Since yesterday all the snaps stopped working. I have an Ubuntu 16.04 LTS installation and the core version is:
core 16-2.32 4308 beta canonical core
The error that all the snaps throw is the following one.
failed to create prefix path: /tmp/snap.rootfs_wHMWrh/var/lib/snapd/lib/vulkan/icd.d: Permission denied
Any suggestion? Thanks in advance!
