After running yum update -y or just yum update -y cronie-anacron, I get the following error:

This line caught my attention

error: unpacking of archive failed on file /etc/cron.hourly/0anacron;56e79ac7: cpio: open

yum is unable to unpack the package. I find out I cannot create files in /etc/cron.hourly/.

# pwd
/etc/cron.hourly
# touch test
touch: cannot touch `test': Permission denied

If I cannot to do this as root, there is something else that is blocking it. Since we run eTrust AccessControl in the server, I decided to turn it off

It works! I don’t know why but if you are running eTrust AccessControl and you are stuck with something when everything else looks good, turn off eTrust.

Turn on eTrust
