"switch_alt_group: Assertion `curpkgd' failed." when uninstalling a package
On Void Linux x86_64 (GLibc), xbps-0.59.1_2, today I hit this assertion when trying to uninstall some packages which are no longer in the repo.
Captured output of what I did:

Hopefully I'll be able to provide more info on request.
Running xbps-alternatives -l after the above leads to another assertion:

It either erroneously called switch_alt_group or that function should know how to deal with cases like this. I will try to reproduce this one.
I believe (but you're better off waiting for someone who understand XBPS better) you might be able to finish uninstalling these packages if you force reinstall them (assuming they are still in your cache), then remove them again. But perhaps leave the PyQt4 package alone. Also, you should probably make a copy of your database if you decide to mess with this stuff, it's in /var/db/xbps/pkgdb*.
Thanks for your suggestions.
I have forcibly reinstalled python3-PyQt4 from my cache using xdowngrade from the xtools package (without doing this I couldn't install anything anyway, as xbps-install would complain about python3-PyQt4 package being broken), and successfully uninstalled all other packages in my original list except for this one.
Sadly the problem persists, trying to uninstall python3-PyQt4 produces the same error. At least xbps-pkgdb -a now no longer complains about files for the other packages.
Could you share your pkgdb? I believe it would help with diagnosing your issue.
@ericonr I'm sorry for the very long delay answering your question.
I'm still experiencing problems with xbps-alternatives -l erroring out.
I have created a repository on Github with the contents of my /var/db/xbps directory as of today, I hope this can be of some use.
From some digging in the XBPS source (sadly I've lost my notes about it), I have a hunch that the problem is somehow related to a situation where the _XBPS_ALTERNATIVES_ key/dict is left with references to non-existent packages. I think this can happen when:
- some update to package X in a remote repository removes its
alternatives - the user first syncs remote repositories, without touching package X
- the user then uninstalls package X
As a kludge, any of following works:
-
cd $(mktemp -d) && xbps-create -n python-PyQt4-1_1 -s pyqt4 -A noarch . && xbps-rindex -a *.xbps && xbps-install python-PyQt4 -R . && xbps-remove python3-PyQt4 && xbps-remove python-PyQt4 - backup /var/db/xbps/pkgdb-0.38.plist, then remove python-PyQt4 entry from
_XBPS_ALTERNATIVES_, then remove python3-PyQt4
Proper fix is unlikely to appear soon.
I can confirm the second approach worked. I removed both the key and dict for pyqt4 and xbps tools started working again.
Problem occurs in following way:
- update package from version defining alternatives to newer one that do not define, using xbps < 0.58 (fixed by #179). After that step,
_XBPS_ALTERNATIVES_in pkgdb lists packages it shoudn't. - remove that package
- attempt to remove other package, such that previously removed package is selected as alternatives provider. Observe crash.
Draft of crash fix is sent in #457.
