Hey guys,
I had a question in another thread about what package might seize up my laptop (with make and model) etc. because when I do an update out of an rpm repository something is sneaking it that freezes it. Nobody could help, so I want to try something else;
Is it possible to track what RPMs you've installed, I can carefully update with a record of what's gone in, and is there a way to roll back (it doesn't need to be easy, just possible) if I get whatever it is that freezes me?

The command "rpm -qa" will list the installed packages. You can also browse your rpm database using the MCC.

There are a number of other ways to use the "rpm" command. You can find which package supplied a program or file with the "rpm -qf <filename>" command. You can also verify packages, "rpm -q --verify <package>" or "rpm -q --verify --all". The later command might show up missing files.

One thing to look for after upgrading a package is for a configuration file with a .rpmnew extension. You may need to add changes to the old config file to the new one, or at least examine the .rpmnew file before copying it to the new one. Enter "locate rpmnew" and see if there are any config files that you need to look at.

If these things don't help, read the "info rpm" manual for the --oldpackage option. Also, consider uninstalling the package you installed and re-installing the version that your distro uses.

Maybe you should have supplied a link to your earlier post.

Good Luck!
