Topic: Can't update 7.51, can't upgrade to 8. Broken Server?

[chris burnat]

Ok, looks like yum is broken. 
The fix in Bug #6892 comment #19 may work for you.
It may possiblu make things worse....
I think this should go to Bugzilla.
Now.
Thanks.

So I will.  Posting follow-up shortly.

Hm.  Getting tired of this.

From the yum website I find:

--nodeps is only used when a package or system is badly broken. As a general rule if you find you cannot put the screw in the hole with a screw driver you should not go get a hammer.

--force tells rpm - if there are any pkg or file conflicts just blow them all away with what I'm giving you. Again - not a good idea if you want to keep your system running well. It's like gardening with a backhoe.

When you go to update yum relies on an assumption that the rpmdb is roughly correct. We've added functionality to warn you when we notice your rpmdb does not have dependency closure - but it is likely that using --nodeps and --force will screw up updates.

But these are rpm options not yum options.  I think I'll have to scrub each package that has dependencies...

[FreakWent]

... and removing every package that wanted dependencies allows the upgrade to continue, EG:

Code: [Select]

xz-libs                 i386       4.999.9-0.3.beta.20091007git.el5  smeupdates-testing  100 k

I'll be in touch.  I'm half expecting this to all go horribly bad.

This is fair enough.  However, please do not post until you have fully solved your issue.  You methodology may or may not be correct, and others users may become confused, or worse may follow you and potentially wreck their system. 
Happy Easter.

Code: [Select]

-bash-3.2$ cat /etc/e-smith-release
SME Server release 8.0beta7

Each package that wanted unmet dependencies has been removed.

rtorrent is broken, with "error while loading shared libraries: libldap-2.2.so.7", which I can deal with one way or another.

rutorrent works, cups is broken. nmap was explicitly removed, so of course it's gone.

I can't think of any other additions I have to the server that I still need to test.

Of course, it might be terribly hard to get my customisations and extensions working again, I don't know yet.

What I did to force my update was clearly "unsupported", and now I'm on a beta release.

I'm not recommending this approach for any business-type production server, but then again a business-type production server probably wouldn't need rtorrent or nmap or any of the rest of my silly rubbish either!

Anyway, I got where I wanted to be.  Cheers!
