atlas-lapack how do I replace a package without uninstalling it ?

Hey all,

the package <b>atlas-lapack</b> doesn't install because of a conflict with blas, lapack, and cblas,
in fact is stated that atlas is a replacement of them.

> error: failed to commit transaction (conflicting files)
> atlas-lapack: /usr/include/cblas.h exists in filesystem (owned by cblas)
> atlas-lapack: /usr/lib/libblas.so exists in filesystem (owned by blas)
> atlas-lapack: /usr/lib/libcblas.so exists in filesystem (owned by cblas)
> atlas-lapack: /usr/lib/liblapack.so exists in filesystem (owned by lapack)
> atlas-lapack: /usr/lib/liblapack.so.3 exists in filesystem (owned by lapack)
> atlas-lapack: /usr/lib/liblapack.so.3.9.0 exists in filesystem (owned by lapack)
> Errors occurred, no packages were upgraded.

The author suggests to uninstall blas, lapack, and cblas, but I can't because  the lapack library on my system follows this dependency chain:

<code> blas -> lapack -> suitesparse -> gegl -> gimp, libmypaint </code>

A small additional note: the atlas library is a 9 hours installation and so I'd hope not to have to reinstall it again.

The question was originally posted here
https://aur.archlinux.org/packages/atla … ent-847732
but I haven't received an answers yet.

Thank you

You could just temporarily uninstall libmypaint and gimp (along with their dependenceis blas, lapack, etc).  But I'd just remove blas, cblas, and lapack with `pacman -Rdd ...`, then install your built atlas-lapack package which will then satisfy those dependencies.

As for the markdown question, the forums do not use markdown, but BBCode which has a link to some usage information right under every text entry box for posting.

The PKGBUILD should declare the packages it conflicts with: https://wiki.archlinux.org/title/PKGBUILD#conflicts

This is a packaging error. The AUR packages should list the packages it conflicts with, then pacman will ask you to uninstall those when you install this one.
