error: failed to prepare transaction (could not satisfy dependencies)
:: installing libjpeg-turbo (3.0.0-1) breaks dependency 'libjpeg-turbo=2.1.5.1' required by lib32-libjpeg-turbo

Hi there, I've got this error doing an update. I have looked around, and i see a similar error posted here: https://bbs.archlinux.org/viewtopic.php?id=283881 which also points to the Wiki https://wiki.archlinux.org/title/Offici … positories

My pacman.conf doesn't have any testing enabled:

#[core-testing]
#Include = /etc/pacman.d/mirrorlist

[core]
Include = /etc/pacman.d/mirrorlist

#[extra-testing]
#Include = /etc/pacman.d/mirrorlist

[extra]
Include = /etc/pacman.d/mirrorlist

# If you want to run 32 bit applications on your x86_64 system,
# enable the multilib repositories as required here.

#[multilib-testing]
#Include = /etc/pacman.d/mirrorlist

#[multilib]
Include = /etc/pacman.d/mirrorlist

I don't think my system ever did, but i followed the advice posted on that thread via the Wiki tried

$ pacman -Syuu

But that didn't change the output, so i guess it couldn't revert anything.

I think that the solution is to remove something, but my brain can't figure out which, or if that's even right. Do i manually remove

libjpeg-turbo=2.1.5.1

and

lib32-libjpeg-turbo

and then re-install

lib32-libjpeg-turbo

? I'm not sure what this software is used for - i don't think i selectively chose to install it, i gather it must be used by something else i use.

Thank you

You have packages installed from multilib, but you don't have multilib enabled. You either need to re-enable it (the include isn't enough) or uninstall everything you have installed from there.

omg.

I came to the right place! (Newbie Corner).

What an oversight. Thank you

For other noobs who might come here:

#[multilib]
Include = /etc/pacman.d/mirrorlist

Should be:

[multilib]
Include = /etc/pacman.d/mirrorlist

(remove the #)
