OPKG segfaults when starting

pjfg · October 26

Hi all,

I have an old NSA221 and I wanted to try to replace the old samba v1 with v2 through entware. However when running opkg via ssh I get a "Segmentation fault (core dumped)".

The log looks like this

I have rebooted, wiped everything from /opt and then dis-&reenabled the entware packet but the problem persists. Having not much of a clue this looks a bit as if the executable/libs from entware itself and the libs from the ddns repo are not working together? Might this be due to an update to entware?

Thanks in advance for any hints

Might this be due to an update to entware?

Don't think so. As you can see at http://pkg.entware.net/binaries/armv5/ nothing has changed since 2018.

When starting the Entware-ng package, the script /usr/local/zy-pkgs/etc/init.d/Entware-ng is executed. This script creates a symlink /opt to /usr/local/zy-pkgs/opt/ and then wants to execute /opt/etc/init.d/rc.unslung (which on his term executes all start scripts in /opt/etc/init.d/). The absence of this script is the trigger to install Entware-ng.

Your log is clearly not a 'clean' install, as /opg is not empty. Yet that shouldn't be a problem as it just installs the same content another time. The file /opt/etc/init.d/rc.unslung is part of the package entware-opt, which is installed as last package. But in your case that is never reached.

I have seen Segmentation fault's here before, and when I remember well that was caused by an empty file, somewhere. Have you checked in the installed /opt/ directory if all files looked healthy?
