[newbie] YUM hangs, can't update without reboot with selinux=0

Hello Everyone!

Apologies for my lack of knowledge. If you are inclined to reply RTFM!, 
by all means do so, but include a link to TFM, please :-)

When I run YUM, it runs briefly, then just sits there. Even when I do 
'setenforce 0'. If I reboot with selinux=0 and the command line, it 
works. I can't find any complaints in any logs (tips on this 
appreciated too). Is there a way to allow updates without two complete 
shutdowns plus a file fix?

Thanks in advance,
   JJ

And if you do a 'touch /.autorelabel; reboot' and do *not* pass
selinux=0, then yum hangs again?

My suspicion is that you had some other random problem such as a lack of
disk space or stale lock file or something, and the time you rebooted
with selinux=0 the problem went away for reasons unrelated to SELinux
(such as tmp/lock file cleanup on reboot).

That worked Colin, thanks!

Even up2date works now. Maybe I'll find out why after learning more 
about SE.

Thanks again!

Again, I don't think your problem related to SELinux at all.  

My suggested command should have essentially just restored your system
to its state before you booted with selinux=0.

In the future, I'd suggest trying other solutions before rebooting with
selinux=0, particularly if you don't see any "avc: denied" messages in
your system log.

[Daniel J Walsh]

You should always try enforcing=0 at the command line
or setenforce 0
To turn off selinux enforcing mode and then see if the problem goes away.  selinux=0
should always be a last resort, since if you want selinux turned back on you will need a
relabel.
