I corrupted my syslog-ng installation so I attempted to uninstall it to then reinstall it however YUM seems unable to remove it from its db.

[root@linux Alex]# yum remove syslog-ng
....
Running Transaction
error reading information on service syslog-ng: No such file or directory
error: %preun(syslog-ng-1.6.9-1.el4.kb.i386) scriptlet failed, exit status 1

Removed: syslog-ng.i386 0:1.6.9-1.el4.kb
Complete!

So I manually remove syslog-ng and then tried to reinstall syslog-ng through YUM and it won't install because it believes it is already installed.

Can someone tell me how I can remove syslog-ng from YUMs db so I can have a clean installation.

Yum uses rpm under the covers, so:

rpm -e syslog-ng

However, I suspect that the messages are actually from rpm, so an rpm database rebuild might be required. If so (as root):

1. rm -f /var/lib/rpm/__db*
2. tar czvf /root/rpmdb.tar.gz /var/lib/rpm
3. rpm -vv --rebuilddb

If the rebuild goes well, you can

rm -f /root/rpmdb.tar.gz

Thank you for your reponse. I had run the first command and received this error:

[root@linux ~]# rpm -e syslog-ng
error reading information on service syslog-ng: No such file or directory
error: %preun(syslog-ng-1.6.9-1.el4.kb.i386) scriptlet failed, exit status 1

This error was similar to the YUM error when trying to remove the software.

I used your syntax to rebuild the db however even after that, I received the same msg from yum when trying to reinstall syslog with the yum install syslog-ng command.

I have searched high and low for syslog-ng's presents on the box and have made sure it has been removed. Only in this database does it reside and give problems.



is there anything else I can try?

Thanks!

--noscript worked perfect for me.

Thanks guys!!!
