How to force install conflicting packages with pacman?

Ashark · 2019-06-18 08:59:32

I am in situation that I need to install a package, which conflicts with another package that is installed.
I know what I am doing and want to force install my package. But I cannot see such possibility.

There is --overwrite option, but it is irrelevant to my case. And there are no actually conflicting files in conflicting packages that I am talking about.
I want something like --assume-uninstalled or --ignore-conflicts option.
Is there a way to do so? Or should I create a feature request for pacman project?

Fix the packages, if they are not actually conflicting then their PKGBUILDs should be fixed to not be conflicting.

Also post a tangible actual real word example, questions like these without context often miss the bigger picture.

But we don't know what you are doing. Why do you want to force it? If it conflicts, why can't you just uninstall the other package? If it is a dependency for another package, will uninstalling it not break that dependency?

The real world example is the following: previously I have installed amdvlk package, which contained the following array: conflicts=('amdvlk-git' 'amdvlk-deb' 'vulkan-amdgpu-pro' 'amdgpu-pro-vulkan').
Now I am preparing amdgpu-pro for arch. And there is a proprietary implementation there. I have created a vulkan-amdgpu-pro package (locally, not yet in aur) which is not conflicting and will not be conflicting with amdvlk. I wanted to install it to be able to test two implementations.

Yes, the PKGBUILD of amdvlk package should definitely be fixed. I will ask a maintainer. Of course I can rebuild amdvlk with edited conflicts array. But I was just wondering if it is possible to force install conflicting packages with pacman.

It used to be, but that option (--force) was removed because it was misused and caused more problems than it solved.

If you "know what you are doing", you could remove the %CONFLICTS% declaration from the installed package's database entry, but that's a hacky workaround. The correct solution is to fix the package(s).

@WorMzy I see, it warns that --force is deprecated and instead of force installation asks if I want remove previous package.
Thanks for idea. But yeah, in my case it's easier to just rebuild a package.

A little late but curious if (-dd to skip all checks) would work for this? I've never used (needed) dd with -S, only -R.

pacman -Sdd <package>

$ pacman -Sh
usage:  pacman {-S --sync} [options] [package(s)]
options:
  -b, --dbpath <path>  set an alternate database location
  -c, --clean          remove old packages from cache directory (-cc for all)
  -d, --nodeps         skip dependency version checks (-dd to skip all checks)
...
...

Edit: Not to imply this would be a better solution than fixing the actual issue here.

NuSkool, the -d flag is for skipping dependency checks, it has no impact on checking for conflicting packages.

There is no way to ignore conflicts, nor has there ever been. --force had nothing to do with conflicting packages.

I had the issue of a self-created AUR package which had wrong conflicts declarations but also failed to compile now.
If you are really sure what you are doing, this can be fixed by editing `/var/lib/pacman/local/<package>/desc`
