I've been dealing with an intermittent bug where my Brave snap seems to lose permissions and can't open. I can fix it by reinstalling Brave, so I've been lazy about reporting this one.

I'm not sure if this is a Solus issue, a Snap issue, or a Brave issue. If it's Brave or Snap's fault, I'll hassle them.

Here is the error output:

main.go:192: cannot change mount namespace of snap "brave" according to change mount (/var/lib/snapd/hostfs/usr/share/fonts /usr/share/fonts none bind,ro 0 0): permission denied
main.go:192: cannot change mount namespace of snap "brave" according to change mount (/var/lib/snapd/hostfs/var/cache/fontconfig /var/cache/fontconfig none bind,ro 0 0): permission denied
cannot update snap namespace: cannot drop supplementary groups: operation not permitted

I am on Solus MATE, and I ran updates yesterday. Kernel is 4.9.124-106.lts. I am willing to provide more OS and hardware details if needed.
