Segmentation fault

[nordicruler]

Im suffering from a world update gone bad. Can someone help me recover from this?

Code: Select all

Emerge gives segmentation fault
emerge --sync seg fault
emerge --info seg fault
revdep-rebuild seg fault
gcc-config -l gives
* gcc-config: Could not get portage CHOST!
* gcc-config: You should verify that CHOST is set in one of these places:
* gcc-config:  - //etc/portage/make.conf
* gcc-config:  - active environment

well, to get things started, lets go to the wiki: "Fix my Gentoo". Since it seems your box is booted you don't need to grab a livecd, but the general idea of grabbing a stage3 and setting up a chroot with it (be sure to copy /etc/portage to your temporary chroot!) to rebuild portage and/or python (or potentially other critical packages like in the system set). since emerge is broken you'll have to use tar until you get it fixed.

nordicruler,

Exacty what caused the segfault will be at the end of dmesg.
Please post the end of dmesg or put it all onto a pastebin.

-- edit --

It might be possible to call emerge directly or emerge may word with other python versions.
You should at least two installed.

Lets see what's broken first.

Hey, I have same problem here.
My "main" gentoo works fine, but there is a segfault error on the copy of gentoo. I made copy to other partition for some tests (changing profile, DE, etc.). When I try to emerge smth after chrooting to that copy I catch a segfault error.

The last messages of dmesg on chroot shows:

[ 347.047496] show_signal_msg: 36 callbacks suppressed
[ 347.047504] emerge[6390]: segfault at b0 ip 00007fb1a5a77b05 sp 00007ffc3a8de170 error 4 in ld-2.29.so[7fb1a5a6d000+1e000]

[ 524.254359] ntfs: driver 2.1.32 [Flags: R/W MODULE].

How to solve that?

Hi. I had the same problem. I found it was due to a bug in openssl-1.1.1a. To fix it I did

* wget http://packages.gentooexperimental.org/ ... .0.2r.tbz2
* tar xvf openssl-1.0.2r.tbz2
* from the extracted dir, copy lib64/libssl* and lib64/libcrypty* to /usr/lib64/
* make sure /usr/libb64/libssl.so and /usr/lib64/libcrypto.so (and perhaps also libssl.1.1.so) points to the extracted so files (libssl.1.0.0.so, libcrypto.1.0.0.so I think).

Now emerge works again and you can unmask openssl-1.1.1b-r2 and do an emerge -uDN @world to fix the system.
