This is a snap based on its location. Snaps are sandboxed and the proper way to remove them is to do a sudo snap remove mysql

snaps are all mounted read-only.

Check this command:

mtodorov@efk:~$ mount | grep snaps
/var/lib/snapd/snaps/hello_20.snap on /snap/hello/20 type squashfs (ro,nodev,relatime,x-gdu.hide)
/var/lib/snapd/snaps/canonical-livepatch_88.snap on /snap/canonical-livepatch/88 type squashfs (ro,nodev,relatime,x-gdu.hide)
/var/lib/snapd/snaps/hello_38.snap on /snap/hello/38 type squashfs (ro,nodev,relatime,x-gdu.hide)
/var/lib/snapd/snaps/core_8039.snap on /snap/core/8039 type squashfs (ro,nodev,relatime,x-gdu.hide)
/var/lib/snapd/snaps/canonical-livepatch_90.snap on /snap/canonical-livepatch/90 type squashfs (ro,nodev,relatime,x-gdu.hide)
/var/lib/snapd/snaps/core_7917.snap on /snap/core/7917 type squashfs (ro,nodev,relatime,x-gdu.hide)
mtodorov@efk:~$

As you see, all snaps have first option ro among (ro,nodev,relatime,x-gdu.hide) mount options, which is a shorthand for "read-only".

Hope this helps.
