Breakage on skipping a package upgrade: "no results found for error)"

[neitsab]

Hi, when asking pacaur to skip a problematic package "upgrade" (it was a fresh installation actually) it ended up on this error:

:: The following package cannot be upgraded due to unresolvable dependencies:
      haskell-gitit

:: Do you want to skip the above package for this upgrade? [y/N] y
looking for inter-conflicts...
 there is nothing to do
:: Package(s) error) not found in repositories, trying AUR...
:: resolving dependencies...
:: no results found for error)

Answering No probaby gives a better idea of where the problem stems from:

:: The following package cannot be upgraded due to unresolvable dependencies:
      haskell-gitit

:: Do you want to skip the above package for this upgrade? [y/N] n
error: failed to prepare transaction (unexpected error)
:: Package(s) error) not found in repositories, trying AUR...
:: resolving dependencies...
:: no results found for error)

Doing the same in French and English. Maybe an incorrect handling of space in a certain string?

Hi, thanks for the report. Someone else reported a somewhat similar issue in the AUR comments a few days ago, but I can't reproduce.

From what I can see in the debug output, pacman finds the haskell-gitit package but can't resolve its dependencies tree. In turns, the error code is passed to pacaur that tries to find that "package" in the AUR.

The responsible part of the code is in ClassifyPkgs(), which isn't robust enough to take care of "unexpected" pacman errors.

However, I'm not sure why this error happens in the first place. The haskell-gitit package doesn't seem to exist at all, and pacaur correctly stops on my machine. If this constantly happens on your machine, could you tell me more about your haskell packages (haskell binary repository enabled?, ...).

[rmarquis]

Relevant commit here: 5987e2a.

It's kind of easy to make the current code robuster, but it breaks translation support. I'll need to figure out another way of handling this issue.

[neitsab]

Thanks for your quick answer, as always.

In an effort to remain concise I forgot to mention the context: haskell-gitit is indeed not part of the official repos but provided by the ArchHaskell group, which maintains two haskell repos (-core and -happstack). This is why you can't find it, you would need to add them to your /etc/pacman.conf file in order to check them.

I enabled those repos in order to get easier access --well, to get any access actually-- to the two following packages found in the AUR, but uninstallable as is: haskell-pandoc and gitit, which relies upon the former.
Their PKGBUILDs are among the most "lacking" I've stumbled upon, with many missing deps and a need to be entirely rebuilt each time one is updated... So the recommended solution is to get them from the custom repo.

Anyway, I suspect this has mostly to do with the packages' metada in the ArchHaskell-provided repos. I sent an email yesterday to their mailing list but it seems I have to subscribe first for my message to appear there (ugh).
I'd rather not have pacaur localisation removed just for this marginal breakage, which doesn't disturb at all its use with "correct" packages. I just wanted to report this bug and give some debug information in case of, but there are more importants issues to be dealt with I believe :-)

Thanks

[rmarquis]

Thank you, I can indeed reproduce the problem now.

Yes, the main issue seems due to inconsistencies in the additional Haskell repositories themselves. I had seen a somewhat similar issue in the past (to make it short, I was playing badly with local built packages) and I deemed it not worth fixing, but this is the first time I see an entire repository causing an error. This is an exceptional situation, but the fact that pacaur code isn't robust enough to handle it is a flaw and should be fixed.

There are many parameters to take into account in order to fix the current ClassifyPkgs() code and it isn't trivial, but I'll have a look.

[neitsab]

Interesting. I appreciate your consideration for this, robutness is of course an always sought-after aspect of a software. I hope you'll manage to wrap your head around this particuliar issue.

[djmattyg007]

I regularly encounter this issue, except with "dependencies)", not "error)". I've never looked into the cause though. I'm not using any custom repositories.

[rmarquis]

@djmattyg007 > Which are the repositories enabled? Or with which packages does that issue occur?

[djmattyg007]

@rmarquis I have core, extra and community enabled. I'm running a 32-bit
system, so have no need for multilib.

Please provide a debug output if the issue occurs again (bash -x pacaur your_command). I cannot do anything without more information.

[rbieb]

Result of "bash -x pacaur -Syu" : https://paste.ee/p/yfht3

I did not actually skip an update. The custom repositories I have enabled are:

• repo-ck
• infinality-bundle
• infinality-bundle-fonts
• multilib

[rmarquis]

@Nordic89: First, ensure to rebuild expac. The new version is still in [testing]. Alternatively, install expac-git from AUR, or wait that the new expac arrives in [extra].

Yes, pacman 4.2 and the new libalpm has arrived.

Please confirm if this solves the issue for you.

[kiicia]

I've just got the same message from pacaur (:: no results found for error).

I was trying to upgrade my system with pacaur -Syu after holiday break but after normal pacman update, after :: Starting AUR upgrade... I got some errors related to being unable to run pacaur due to pacman local files consistency... I missed exact error TBH. I fixed (?) it by regenerating pacman db and keyring.

But even after that I am unable to get rid of that last :: no results found for error...

Here is full output: https://paste.ee/p/8oWel

[rmarquis]

Pacman 4.2 has landed in [core], and thus cower must be recompiled, and you need expac 4-3 (which is now in [extra]).

Please don't report issue until you're sure you've done your pacman/cower/expac update homework.

[kiicia]

Yeah, I saw that a second after submitting above comment, sorry.

I am trying to cleanup and upgrade everything properely now, still have some problems with signatures tho...

[ronjouch]

Same issue, recompiling cower worked for me. Thanks for the help and for pacaur :)

[rmarquis]

Since the ClassifyPkgs() function use the "pacman -Sp" function more or less as a hack to:

• check for existing binary packages
• handle providers
• handle versioning
• handle groups
• handle repo/package syntax

I'll need a replacement function that handles all of these, plus handles the errors correctly.

Two possibilities:

• pacman -Sp call could be modified so it doesn't stop at errors (but also displays correct results), and check for binary packages first, instead of non-existing binary packages.
• expac could be expanded to support versioning. This is probably the preferred option.

[rmarquis]

This bug is very tricky to solve. Reimplementing it in another way with all the supported features clearly gives me headache.

As a workaround, I've implemented an early check in a1c53bc that ensures the package name doesn't contain ")". It should catch the binary repositories errors. This won't catch libalpm upgrade issue, but that's a different situation.

Closing, please reopen if this happens again (and attach full details).

[rmarquis]

Polish translation broke because the error string isn't similar anymore to the English string. See #302.

The ClassifyPkgs() needs to be made more robust in some way. Polish translation will be disabled in the meantime. Alternatively, drop translation support entirely.

[xinulsw]

I don't know if this is relevant with reference to broken polish translation, but when installing returns error "no results...", updating with command pacaur -Syu works. Today for example i've tried install xfce-theme-greyibird with no luck, but upgraded it successfully.

[rmarquis]

@xinulsw > When you get the chance next time, I'd appreciate to see a debug output. Both install (-S) and update (-Syu) commands call the same ClassifyPkgs() function.

[xinulsw]

błąd: pakiet xfce-theme-greybird-git nie został znaleziony in english: error: package ... was not found.

Unfortunately i haven't any package right now to upgrade... but i'll post debug as soon as I can.

[rmarquis]

Thx. See https://wiki.archlinux.org/index.php/Pacaur#Bug_reports for debug output. The pacman --debug flag is absolutely worthless when debugging pacaur.

[xinulsw]

Sorry for bloating, here correct debug I hope:

I havent used pre and code tags because in preview log have been cut off.
In next comment i'll post debug for upgrading package.

[kyak]

$ LANG=C pacaur -S nvidia-ck-ivybridge

This message i have seems relevant to this issue. I do really have the dependency conflict, but that's not the point.

[rmarquis]

Yup, seems to be the very same issue.

Here is a more common, related error when making use of the IgnoreGroup config option:

$ pacaur -S kcm-fcitx
resolving dependencies...
warning: ignoring package fcitx-qt5-1.1.0-1
warning: cannot resolve "fcitx-qt5", a dependency of "kcm-fcitx"

looking for conflicting packages...
 there is nothing to do
:: Package dependencies) not found in repositories, trying AUR...
:: resolving dependencies...

[rmarquis]

pacsift from pacutils can be used to finally fix this issue. Delaying to pacaur 5.0.
