How to find the package that required a package that caused a conflict?

Silnar commented 8 years ago

Hi, I'm trying to update AUR packages, but I've encountered the following problem:

LANG=C pacaur -Sau                                                                                                              ⏎
:: Starting AUR upgrade...
:: resolving dependencies...
:: looking for inter-conflicts...
:: mesa-libgl and catalyst-libgl are in conflict (libgl). Remove catalyst-libgl? [y/N] n
:: unresolvable package conflicts detected
:: failed to prepare transaction (conflicting dependencies)
:: mesa-libgl and catalyst-libgl are in conflict

Could you tell me how can I find the AUR package that requires mesa-libl ?

You guys are killing me. See #515.

Hopefully not :smile:

I think that you did't understand me correctly, so here you have a better explanation.

I encounter this problem twice a year and never know how to solve it quickly.

Ideally I would like to see message like

:: mesa-libgl (required by ??) and catalyst-libgl are in conflict (libgl). Remove catalyst-libgl? [y/N] n

where ?? is the name of AUR package that pacaur is trying to update. It would be helpful to know the name of this package, so I can remove it for example.

It's easy to get a list of packages that requires catalyst-libgl with pacman -Sii package-name:

LANG=C pacman -Sii catalyst-libgl

but searching for AUR packages in similar fashion using pacaur doesn't return anything:

LANG=C pacaur -Saii mesa-libgl
:: no results found

To sum up:

I'm updating aur packages
I know that at least one of them requires mesa-libgl and causes conflicts
I don't know which one

Cheers.

In that case your request in similar to #173. And there is no easy way to achieve this, as the RPC interface is quite limited.

Ok. I see. Thanks for info.
