[SOLVED] pacman -Suy ==> :: clingo and clasp are in conflict.

newsboost · 2017-06-14 00:09:09

Hi all,

Sorry, I cannot upgrade, here's what I did and the output:

# pacman -Suy
:: Synchronizing package databases...
 core is up to date
 extra is up to date
 community is up to date
 multilib is up to date
 blackarch is up to date
:: Starting full system upgrade...
warning: metasploit: local (4:39481.d2100bf-3) is newer than community (4.14.21-1)
:: Replace wxgtk with extra/wxgtk2? [Y/n] 
resolving dependencies...

warning: removing 'clasp' from target list because it conflicts with 'clingo'
:: clingo and clasp are in conflict. Remove clasp? [y/N] 
error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: clingo and clasp are in conflict

I don't understand why this is marked as "resolved" under https://bugs.archlinux.org/task/54310 but still it does not work, as there's still a conflict? Then I tried:

[root@HPpc martin]# pacman -R clasp
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: aspcud: removing clasp breaks dependency 'clasp'

I don't understand the message that removing "clasp" cannot be done, because it breaks dependency "clasp"? I thought it would only be a problem, if *another* package depended on "clasp" - but as it only depends on itself, I don't see why it cannot remove this package?

Please advice, I've been pulling my hair the last days due to this, so I would be grateful for help/ideas in this matter, thanks!

I believe it's saying the package "aspcud" depends on "clasp".

shmibs · 2017-06-14 00:17:23

the line

:: aspcud: removing clasp breaks dependency 'clasp'

means that the package aspcud has a dependency 'clasp' which will be broken by removing clasp.

in general, if you want the list of packages which depend on or are required by a particular package, you can get it by running:

pacman -Qi <packagename>

Clingo provides `clasp`, so you could answer "y" when it asks you whether it shall replace clasp with clingo.

That conflict was added fairly recently (although I admit that I'm always pretty confused by the history in official packages).

--edit: I guess that both packages are installed on your system right now. See shmibs' post for checking why they had been installed in the first place.

After I while, I realized I had to get rid of those packages it complained about (then I must re-install later if necessary, now it's been to long ago I last updated):

# pacman -R opam aspcud clasp clingo
checking dependencies...

Packages (4) aspcud-1.9.1-1  clasp-3.2.1-1  clingo-5.1.0-1  opam-1.2.2-2

Now I tried:

# pacman -Suy

:: perl-gtk2-unique: installing perl (5.26.0-1) breaks dependency 'perl<5.25'

Eventually I discovered I needed to remove these packages + shutter (didn't work without removing shutter, I could use the "-Si" option to see some packages were required by shutter):

# pacaur -R gnome-perl gnome-vfs-perl gnomecanvas-perl perl-gnome2-wnck perl-goo-canvas perl-gtk2-imageview perl-gtk2-unique shutter
checking dependencies...

Packages (8) gnome-perl-1.045-4  gnome-vfs-perl-1.082-4  gnomecanvas-perl-1.002-14  perl-gnome2-wnck-0.16-11  perl-goo-canvas-0.06-7  perl-gtk2-imageview-0.05-7  perl-gtk2-unique-0.05-13
             shutter-0.93.1-3
...

Then "pacman -Suy" now worked! After updating, I made "pacaur -S shutter" and rebooted (as it was a pretty big update, 1.3 GB download or 5 GB installed)... Now I've just rebooted and it feels so very nice, when the whole system is up-to-date, thanks a lot everyone - I'm grateful for your help, problem is solved!!!
