Description Matěj Cepl 2017-04-24 17:13:10 UTC
Description of problem:
SELinux is preventing /usr/bin/python2.7 from 'execute' accesses on the file /usr/bin/hostname.

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

If you believe that python2.7 should be allowed execute access on the hostname 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 'rhsmcertd-worke' --raw | audit2allow -M my-rhsmcertdworke
# semodule -i my-rhsmcertdworke.pp

Comment 5 Kevin Howell 2017-05-05 20:43:05 UTC
Unfortunately, this causes inconsistencies in the facts reported by subscription-manager and its daemon (rhsmcertd). The easiest solution to bug 1447722 without regressing on bug 1401394 is to get this bug resolved, though we are open to suggestions for alternative solutions.

Comment 6 Milos Malik 2017-05-09 15:55:09 UTC
I believe this bug is a duplicate of BZ#1445494.

Comment 7 Kevin Howell 2017-06-28 17:42:57 UTC
This was resolved by a different implementation in bug 1445494, so closing as NOTABUG, since the new implementation does not have this problem.
