pacman segfault

Corvin · 2006-09-23 08:39:10

Hi, I am archlinux user from maybe 2 years. I use current and I'm up to date almost ever. From 2-3 weeks something wrong is with packan, every try of pacman -Suy ends with segmentation error (fault). When I run it only from console it writes debug info, and a lots is about reiserfs. I've checked partition and it has no errors. When I don't use pacman Arch is working very good, only one application which crashes is nicotine . It happens on both kernels default and beyond. Any help? Thanks in advance. Ask me or please give me some instructions how to provide additional tests, like a coredump, systrace etc.

try pacman.static -Sy pacman

Ok but what is the diffrence between static and normal pacman. Static I suppose is statically linked, but I don't get it, how it could help?

Corvin · 2006-09-23 17:17:50

pacman.static also causes segfault

Have you tried pacman -Sy followed by pacman -Su ?
that might give some clues where the problem is.

Corvin · 2006-09-23 21:43:42

yes, pacman -Sy with no problem but -Su crashes

Cam · 2006-09-23 23:59:56

strace pacman -Su

if you don't see the problem there put output in a pastebin somewhere

it crashes after last line

Corvin · 2006-09-25 07:38:45

I've probably resolved that issue! I've upgraded by hand sysfsutils and shadow packages and problem has gone!

Snowman · 2006-09-25 15:39:42

Reinstall them with the working pacman:
pacman -S sysfsutils shadow
to make sure that they are installed correctly.
