Description Steffen Scheib 2018-02-08 10:56:41 UTC
Description of problem:
Installed snapd (sudo dnf install snapd). During the installation process several SELinux denials are raised
SELinux is preventing snapd from 'read' accesses on the lnk_file ld-linux-x86-64.so.2.

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

If you believe that snapd should be allowed read access on the ld-linux-x86-64.so.2 lnk_file 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
