Re: [SOLVED] update issue libjpeg-turbo

The virtual libjpeg was removed on purpose , see Remove the provision for libjpeg

Change libjpeg to libjpeg.so or libjpeg-turbo in the PKGBUILD.
Also add a comment about this on the gtk4-git aur page.

Re: [SOLVED] update issue libjpeg-turbo

After changing that in your PKGBUILDs, you need to rebuild and install them. In some affected cases a rebuild may be required simply because the so version has changed.

If you rely on somebody else’s PKGBUILDs (e.g. over AUR) and don’t want to keep your own PKBUILD separate from theirs (for whatever reason), you may temporarily make pacman think libjpeg dependency is satisfied with: `--assume-installed=libjpeg`. This will not help with packages that require a rebuild, This is also a temporary circumvention only(!) — to let the official packages be updated ASAP, while fixing the foreign ones is in progress.

That may also be needed if you don’t build in clean chroot and wish to avoid rebuilding packages twice: once merely to satisfy dependencies, once for the updated libjpeg-turbo.

Re: [SOLVED] update issue libjpeg-turbo

i fixed it by :
octopi
removed gtk4-git
installed gtk4

it looks to me this has already been reported in 2026.
the gtk4 makes firefox look a lot better.

Firefox uses GTK3, so no.

Unless you actually compiled FF from this branch.

Re: [SOLVED] update issue libjpeg-turbo

I had this exact error today. I solved it by replacing electron27 with electron27-bin from the AUR. After that regular updates worked. No editing of files needed.

Re: [SOLVED] update issue libjpeg-turbo

I have similar errors, but others packages are also affected :

error: failed to prepare transaction (could not satisfy dependencies)
:: installing libjpeg-turbo (3.2.0-2) breaks dependency 'libjpeg' required by electron19
:: installing libjpeg-turbo (3.2.0-2) breaks dependency 'libjpeg' required by electron27
:: installing libtiff (4.7.2-1) breaks dependency 'libtiff=4.7.1' required by lib32-libtiff
:: installing libjpeg-turbo (3.2.0-2) breaks dependency 'libjpeg' required by ntk-git
:: installing libjpeg-turbo (3.2.0-2) breaks dependency 'libjpeg' required by xsane

Which package can replace xsane ?

Re: [SOLVED] update issue libjpeg-turbo

Potomac, you don’t have to replace anything. Not due to the issue discussed in this thread, at least.

The packages declare a wrong dependency. That is all! All affected packages did work with libjpeg-turbo for years and, unless API backward compatibility is broken, are going to continue working with libjpeg-turbo for the foreseeable future. It’s an issue in package’s description. You can just rebuild the package with `depends` array corrected to indicate libjpeg-turbo instead of libjpeg.

If you delegate maintaining PKGBUILDs to somebody else (e.g. some AUR user) ping them about the need to make that update. In the meantime you may use my advice above as a temporary remedy where a rebuild due to so version change isn’t needed. Where needed, you’d have to rebuild anyway. With or without the libjpeg dependency situation.

Re: [SOLVED] update issue libjpeg-turbo

Having the same issue with xfig-git (yes, I'm an old fart). Suddenly refuses to build because it cannot find libjpeg.

Looks like I'm going to have to bring this up at the AUR.

Just change the PKGBUILD and

makepkg
sudo pacman -U ******

Good catch.  But, as this is "solved" by the OP I could just close it.  But, there seem to be a couple Arch users still fighting the same issue, so I'll let this stay open -- for now.

Re: [SOLVED] update issue libjpeg-turbo

Keep in mind that the arch repos are listed above chaotic and arcolinux repos, so OP can still be running archlinux.
