Removing AUR package (could not satisfy dependencies)

Ok, this post definitely belongs in newbie lol. I’m still learning how to deal with these scenarios, as it’s not a common one I cross paths with.

I was trying to install libheif on my Arch system to view .HEIC images, and couldn’t remember how I got it working on my other EOS machine. I installed it via yay -S libheif and that was not enough to get it working, so I tried to remove it before trying other methods and I ran into:

[user@Arch ~]$ yay -R libheif
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: removing libheif breaks dependency 'libheif' required by gd
:: removing libheif breaks dependency 'libheif' required by gimp
 -> exit status 1

I tried to mark the dependencies as explicitly installed before attempting to remove the AUR again, but that also didn’t work, as there were other chained dependencies.

Little confused here.

Are you sure that didn’t just reinstall it? Can you still see the terminal output?

If not look at the date of the file in your pacman cache.

libheif is a required dependency of both gd and gimp and is in the official Arch’s repos and not in AUR.

For example:

pacman -Qi gd | grep Depends 
Depends On      : fontconfig  libxpm  libwebp  libavif  libheif

So as mentioned above, you may just have reinstalled it.

Look at the last lines of:

grep libheif /var/log/pacman.log


You can check if a package is in the AUR:

yay -Sia "name-of-a-package"   # note the "a" after "-Si"

Also, a package included in the repos listed in /etc/pacman.conf is found with:

pacman -Si "name-of-a-package"
# or
expac -S %n "name-of-a-package"

A bit more related stuff: you can check if a package is installed on your system with:

pacman -Q "name-of-a-package"
expac "%n %v" "name-of-a-package"

Both of these commands show the same information if the package is installed.

Yeah, I should’ve done that first, but I was just under the impression I didn’t have it installed, since the .HEIC images aren’t viewable in gwenview.

So it doesn’t appear to be in the AUR despite “reinstalling” it from the AUR.

Shows in pacman output, which is a good sign I suppose.

Are the dependencies correct here, or did I change it from the default?

Before making this post I tried sudo pacman -D --asexplicit gimp gd and then to reverse it I ran sudo pacman -Rns gimp gd. Am I good?

Does this essentially mean nothing has changed, and I can just carry on as if I never installed the AUR? I still need to get the .HEIC images to load.

There seems to be some misunderstanding regarding the functioning of yay.

yay is not only an AUR helper targeting packages in AUR. It is also a pacman wrapper meaning it is capable of operating on the packages from Arch’s repos as well.

So, when you run yay -S X, if X is from Arch’s repo, it will be installed from there.


That one flew over my head. I didn’t pay attention to the -S in the yay command, in fact that’s the first time I’ve added -S to yay, but that makes sense now. Thanks for pointing that out.

That being said, I’m still not sure how to get the HEIC images to load.

What application are you trying to use to view them?

gwenview is my default

That also requires kimageformats to be installed I believe.


Thanks. That did the trick.

You always come through :saluting_face:
