Comment on Updating OS EZ Template Caches by mt

Hi,

Try to Rebuild an rpm database using following commands as it seems your rpm database is corrupt.

1) cd /var/lib
2) tar czvf /tmp/rpmdb.tar.gz rpm

( if you do not have much space in /tmp, you can change the path to /root/rpmdb.tar.gz, which is just to keep a backup of current db as a precaution, if the rebuild completes succesfully, you can delete /tmp/rpmdb.tar.gz )

3) cd /var/lib/rpm
4) rm -f __db*
5) rpm –rebuilddb -vv

You might also be tempted to run the following in 6th step ( if the file /etc/init.d/syslog does not exist)

yum install sysklogd

( or yum install rsyslog , if sysklogd is not available )

since it was showing missing /etc/init.d/syslog in the error

Then try to run vzpkgcache again.

Eeek! I tried to follow your tutorial on CentOS 5.3, but vzpkgcache fails with following error:
