Description of problem:
SELinux is preventing snapd from 'remove_name' accesses on the directory names.by1VJ714k18y~.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that snapd should be allowed remove_name access on the names.by1VJ714k18y~ directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'snapd' --raw | audit2allow -M my-snapd
# semodule -X 300 -i my-snapd.pp
