Rollback updates in centos linux 5.x?

TMA · 05-24-2016, 06:00 PM

I ran 26 updates on my linux server and my VPN died....need to roll back the updates to verify that that is not the problem. I am a windows guy and not very fam with Linux. Any help...(please)

I think the command you are looking for is

Quote:

yum downgrade

and I think you need to do this for each package

Would you like to tell us more about the VPN problems? Maybe there is a simple solution. And what packages were updated?

While timl's method is correct,. it will all depend on what yum plugins you have installed. I think 'yum info yum' will tell you which ones are installed,. mind sharing them? If you do not have the correct plugins, then it is going to be a manual affair of looking at yum.log to find out what was upgraded, finding the old packages (if they are still in the yum cache) and replacing them with older equivalents.

Loaded plugins: fastestmirror, priorities, security

Sorry then. For 'yum downgrade' or 'yum history' to work you have to have the yum history plugin installed. Essentially then, there is no automated easy way to roll back the changes. However,. if your VPN is the only thing that got changed, then you are likely just looking at an overwritten configuration file.

What was your VPN software? OpenVPN? Did you set up the config file? Have you went to /etc/ and looked for a backup VPN config file (generally with the extension .bak)?

the old 5 series uses the text logs in /var/log

have a read through yum.log file
at the end will be the most recent

but if you do not inform us as to WHAT "VPN died" means
then there is really NOTHING we can do but make WILD GUESSES

what is the vpn error in the logs ?
