Description Rahul Sundaram 2011-01-23 22:42:39 UTC
SELinux is preventing /usr/bin/python from 'write' accesses on the directory yum.

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

If you believe that python should be allowed write access on the yum 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:
# grep yum /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2011-01-24 15:34:56 UTC
Some how we ended up with a directory names yum labeled rpm_tmp_t?

Probably under run or lib

ls -ldZ /var/run/yum /var/lib/yum

Comment 2 Rahul Sundaram 2011-04-17 12:09:27 UTC
No /var/run/yum

 ls -ldZ /var/lib/yum
drwxr-xr-x. root root system_u:object_r:rpm_var_lib_t:s0 /var/lib/yum
