problems with dependencies?

[hughitt1]

Hi,

i'm trying to install some packages on fedora fc4 using apt / yum, and keep running into dependency errors. This one i can't figure out though because it won't let me remove the bad package..

when i try to install something using apt, i get the error message:

You might want to run `apt-get --fix-broken install' to correct these:
The following packages have unmet dependencies:
xml-commons-apis#0:1.0-0.b2.6jpp_12fc: Depends: xml-commons (= 0:1.0-0.b2.6jpp_12fc) but 0:1.3.02-1jpp is to be installed

so i go to shell and try apt-get --fix-broken install

The following packages will be REMOVED:
xml-commons-apis#0:1.0-0.b2.6jpp_12fc (0:1.0-0.b2.6jpp_12fc)
0 upgraded, 0 newly installed, 1 removed and 59 not upgraded.
Need to get 0B of archives.
After unpacking 3980kB disk space will be freed.

Last, i decide to try rpm:

[root@resnet-10-9-4-86 ~]# rpm -e xml-commons-apis-1.0-0.b2.6jpp_12fc.i386
/var/tmp/rpm-tmp.24182: line 1: rebuild-gcj-db: command not found
error: %postun(xml-commons-apis-1.0-0.b2.6jpp_12fc.i386) scriptlet failed, exit status 127

I'm stumped

Anyone have any suggestions, or run into similar problems? Any help would be greatly appreciated.

Thanks,
Keith

The problem is you're trying to replace a version that is already on your system by another one needed by the program you just installed. I think you installed something that needed to downgrade the xml-commons package, which it did, with as a result broken dependencies. You should find out what program install caused that. Downgrading can give a hell of a dependency problem, trust me .

Sounds like you mixed the RPMForge repositories with extras/Livna. The easiest fix for this is reinstallation then going with one set of repositories.

is there any easy way to reinstall problematic programs without having to wipe the entire system and start fresh?

I doubt it.

Try "rpm -e --nopostun ..." to not run the postuninstall script.

Thanks spoon,

I tried that and it worked fine. I still have about 4930223 other dependency problems, but now at least there is one less, and i was able to install kdegeography

Try "rpm -e --nopostun ..." to not run the postuninstall script.

The nopostun comment was the start of me investigating the --noscripts options, which helped me greatly to get a package uninstalled.

BTW...my first post here.
