I use the haskell-core repository provided by the arch haskell project. For 4 days now I get an error message when I try to update packages with pacman -Syu.
Fehler: Konnte den Vorgang nicht vorbereiten (Kann Abhängigkeiten nicht erfüllen)
:: haskell-pcre-heavy: benötigt haskell-semigroups=0.16.2.2_0-83
(Error: Could not prepare the process (Could not fulfill dependencies) # something like this
As a workaround for some time to see if this is fixed somehow in the next days I tried to put each of them and both together to IgnorePkg in /ect/pacman.conf. However, this did not change anything and I can still not update my system.
Is this problem really a problem of the haskell-core repository or not?
How can I omit these packages being updated so that I can at least update the rest of the packages since IgnorePkg does not seem to work.
Thx

Would you mind to post the entire /etc/pacman.conf?

What's the output of
$ pacman -Ss haskell-pcre-heavy
no output
$ pacman -Ss haskell-semigroups
haskell-core/haskell-semigroups 0.17.0.1_0-1 [Installiert: 0.16.2.2_0-83]
Anything that associates
so yes haskell-pcre-heavy needs haskell-semigroups 0.16.2.2_0-83 which is installed but would probably being updated to 0.17.01._0-1 during the update process why dependency would break. Normally these conflicts are handled very well during update processes. I don't know what is going wron in this case.
However I managed to at least get an update of non haskell-core packages by putting haskell-* to IgnorePkg in pacman.conf. Still the main problem remains intransparent to me.

The pcre-heavy package has been removed from the repo and no other package has been updated to provide the missing package, that's why it can't resolve the conflict (and why -Ss turns up no results)

In the end I uninstalled and re-installed all packages that created an unresolvable dependency chain and afterwards this specific dependency that caused the problem was away.
