installing nettle (4.0-1) breaks dependency

I got this error message some days ago, when running  `pacman -Syu`.

The full message:

:: Synchronizing package databases...
core is up to date
extra is up to date
:: Starting full system upgrade...
resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: installing nettle (4.0-1) breaks dependency 'libhogweed.so=6-64' required by ssh-openpgp-auth
:: installing nettle (4.0-1) breaks dependency 'libnettle.so=8-64' required by ssh-openpgp-auth

What should I do to to resolve the problem?

Thanks.

ssh-openpgp-auth is not in the official repos. This is an AUR package: https://aur.archlinux.org/packages/ssh-openpgp-auth

Thanks, I removed ssh-openpgp-auth.

However I suspect that the package was available in the official repository.

Why pacman did not reported that ssh-openpgp-auth was removed by the official repository?

ssh-openpgp-auth entered aur a year ago.

pacman never reports such things, you're expected to maintain your system. One of the things you should do regularly is running pacman -Qm to look for packages that do not come from repos and check if they are still needed.

I suggest you read https://wiki.archlinux.org/title/System_maintenance thoroughly .

Re: installing nettle (4.0-1) breaks dependency

The underlying reason is that pacman doesn't store or care where a package came from.
Next to pacman -Qm you could cache the databases, diff them against the update and check whether any of the missing packages is installed.
Slight problem might be when packages get moved from core to extra or vv and you get a false positive removal so you'd also have to merge the two diffs for the net loss.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
