I want to try Fedora Core 4, Im currently using Fedora Core 3... what would be recomended? should i just upgrade? or should i do a fresh install? i do have important files in my current linux....

Backup your important files and fresh install. I personally do not care what OS your using. Upgrading an OS is not a good opinion in my idea. Seems to cause problems regarding the OS. Plus, a new install is clean and lean.

I second brianthegreat’s comments.

It’s probably OK to upgrade an X-less server, but something (or lots of somethings) is usually broken after upgrading FC running X. I tried to upgrade several desktop systems from FC3 to FC4 and never got one I was happy with. Besides, it’s often quicker to do a fresh install than it is to upgrade.

thnx i'l keep that in mind, im just a little iffy that i have o do all my configs again on FC 4

Redoing your configs does suck but you would have to bite the bullet sooner or later.

I find the best way to upgrade without optical media and havig to backup lots of config files (if its a server you really should have a backup) is using yum. All you need to do is get the new redhat-release or fedora-release rpm of the new distro version, install it, drop to runlevel 3 and then run "yum upgrade". CentOS uses this metho by default to upgrade from one version to another.

The runlevel 3 idea is a good one that I didn’t try when using yum to upgrade FC3 to FC4.

After installing fedora-release-4, I do recall not being able to get “yum upgrade” to upgrade anything until I installed a kernel from FC4 using yum and booted with it. Then I used “yum remove ...” to remove the old kernel packages. There was a FC3 kernel-utilities (or something like that) package that was getting in the way of the upgrade.

It’s also a good idea to run “yum upgrade yum” before doing the full upgrade.

Yeah, you are absolutely right. The good thing about updating yum is that it should upgrade rpm to the newest version as well before upgrading everything else.

Install the fedora-release rpm for fc4, drop to runlevel 3 (init 3) and do

Code:

#yum clean all
#yum yum
#yum upgrade

jt1020 · 12-09-2005, 04:44 AM

#yum clean all
#yum yum
#yum upgrade

what does this do if you dont mind me askin?

oh and i've read in one of the post above that i should upgrade yum first before upgrading anything else... would it be ok if i do the yum upgrade first before installing fedora4-release RPM?

Based on this post I'm going to upgrade my FC2 to FC3 with a fresh install. I already have a good backup of all my configuration files. If I upgrade, is there a way to import user accounts from my old install to my new one so that my users don't have to setup their profiles again. I don't mind making them change their passwords, but just want their settings to be the same as before the upgrade too place. Any recommendations?

The first command cleans the yum cache which contains info about package headers etc. The second command upgrades yum and the third command upgrades everything installed on your computer thats available in the FC repos.
