Solve “Perl 5.26 Dependency error: failed to prepare transaction (could not satisfy dependencies)” In Arch Linux

Today, I tried to update my Arch Linux desktop, and ended up with Perl dependency problem. However, I never installed those broken Perl packages directly. I thought it was due to pacman problem. After a bit of searching on Arch Linux forums, I found that it isn't related to pacman, but AUR. Here is the error message I got when I tried to update my Arch system.

$ sudo pacman -Syu

Sample output:

The above packages are the dependencies of Shutter screenshot tool. The actual reason of this perl dependency issue is the developer of Shutter has stopped the development two or three years ago. It makes use of a lot of dependencies which makes it very hard to maintain.

To solve this problem, either you should uninstall Shutter, and go for the other alternative, or just remove Shutter and all its dependencies, and then reinstall it again.

To remove shutter, run:

$ sudo pacman -R shutter

After removing Shutter, you need to remove all unused dependencies using command:

$ sudo pacman -Rns $(pacman -Qtdq)

Alternatively, you can only remove problematic dependencies using as shown below. Please be careful while doing this. Just make sure you are removing the correct problematic perl packages only.

$ sudo pacman -R perl-gtk2-unique perl-gtk2-imageview perl-goo-canvas perl-gnome2-wnck gnomecanvas-perl gnome-vfs-perl gnome-perl

This time I updated my Arch Linux box without any issues. After updating the system, you can either find any alternative tool for Shutter or simply reinstall it using Yaourt or Packer.

yaourt -S shutter

Or,

packer -S shutter

Reinstalling Shutter may bring this perl dependency issue again. I recommend you to wait for the official solution. This method will solve the problem temporally.  Or, find an alternative to the Shutter screenshot tool, and get rid of it permanently.

Cheers!
