how to unmerge individual packages (linked to kde-meta)

[moment92]

I unmerged some individual packages, that I do not need. KDE came with lots of programs I want to get rid of. For example, I do not want to use konqueror, but when I unmerged it, I got errors from emerge --depclean. It seems, that the program is linked to kdebase-meta. How can I get rid of it without getting errors, caused by dependencies of meta-packages?

You probably wanted to:

Code: Select all

# emerge -av kdebase-startkde

Rather than kdebase-meta.

I installed kde-meta. Is it possible to unmerge packages without replacing it?

[kingcoras]

you should be able to do this:

Code: Select all

emerge --unmerge kde-meta

kde-meta doesn't actually do anything other than pull all of the KDE packages as dependencies, and removing it simply removes the dependancy chain. afterwards, you should be able to remove the packages that you want, assuming they aren't dependancies for an actual program.

I already tried it. The problem is, that next time emerge --depclean wants to remove 174 packages.

No, that's not possible. Either you want the whole set or you can't use it.

I unmerged meta-package and replaced it with kdebase-startkde. Although it has much less pointless packages, it still annoys me, that I can't remove the packages I don't like.

Of course you can. It just breaks the dependency chain, so you'll have to live with emerge complaining in that case.

Wouldn't it be possible to add the meta dependencies that are wanted to the world file? So you would unmerge the meta file and unmerge the dependencies you don't want. Then see what packages an "emerge -p --depclean" wants to remove and add these to the world file. This used to work years ago but maybe things have changed so much that it no longer works.

No, that should work ok - just emerge --no-replace the ones that you want to keep. Long list though, probably.

Long list though, probably.

That's why we have fancy editors and shells.

Hello,

First, identify what application are you need's to maintain : qlist -I kde-base

Probably you need kdebase-meta (base for all work's)
Identify list of application depend of meta package : qlist -I kde-base | grep meta
And for each meta package : qdepends -I kdexxxxx-meta (kdebase-meta for ex)

Unmerge kde-meta and all meta package that you not needs.

EMERGE kdebase-meta, all meta package that you needs and all major individual package that you needs (to update your world file)

After that a depclean normaly remove only unneeded application

Wouldn't an emerge --no-replace (as wjb suggested) be much better here so you don't have to needlessly re-compile a ton of KDE apps and libs?

[USTruck]

Exact : This is done by unmerge only META package (all meta are installed by kde-meta)
After that, if you run depclean all libraries and application are un-installed (DO NOT USE IT)

To not re-compile all libs and application, emerge needed meta package and individual application.

--noreplace it's best way yes but some dependencies are not installed (or re-installed if necessary)

emerge -uDN to be sure that all dependencies are installed
