EIB segmentation fault

[brononius]

Hey,

Just did some apt-get upgrades, rebooted my server, and my EIB won't start anymore. 
I'm getting a segmentation fault.

   Segmentation fault (core dumped)


Any idea what i'm doing wrong, or what can be done to troubleshoot this?



ps the IP is correct, my core is 192.168.111.1.

Forget to mention that some packages were skipped during upgrade. No idea if it's linked with it.

Poewee, no idea what I'm doing, but with gdb, I'm getting an issue with /usr/lib/libpthsem.so.20?

Holy crap, someone besides posde is using eibd?

The upgrade problems are one issue, the eibd is another.  You didn't mention (and this is *very* important) but I'm going to assume you're on 1404.  We identified an issue with eibd server this weekend, we have no idea what is causing it at the moment.  eibd is working perfectly in 1204 but not in any of the current 1404 builds.  You can install the .deb from the 1204 repo or one from the mkoegler ppa for now.

[phenigma]

The upgrade failures are rather strange, they hint at two things.  1. it looks like you had internet errors during the upgrade, I'm really not sure 2. it looks like you're missing files from the installation, specifically from boot-scripts.

J.

[brononius]

Are there alternatives for eibd?
I don't know any other way how to contact the IP-router of my knx installation.  :$

I'm trying to find out how I can install it directly from kroegler, but I'm always getting the info that i'm already on the latest version. :$

They're already at home complaining that some functions aren't working regarding the ligths and so (you only miss what you've got when it's not there)...


ps see my signature for the version...

[phenigma]

I know of no other way to connect to knx.

apt-get install <pkgname>=<pkgversion>

will install an old version of a pkg.

J.

[phenigma]

Was this working on 1404 for you previously?  If so, do you know the version number of the eibd-server pkg that was working?  0.0.4 or 0.0.5?

J.

[brononius]

Sorry, no clue... :$

[brononius]

Installing the deb package worked to downgrade:

      wget https://www.auto.tuwien.ac.at/~mkoegler/debian/pool/main/b/bcusdk/bcusdk_0.0.4_all.deb
      dpkg -i bcusdk_0.0.4_all.deb

But gives me the same error:

[phenigma]

Try 0.0.5 from mkoegler, that is working for posde on 1404 i386.

J.

[brononius]

It was alread the 0.0.5 (what I did before):

but after installing the libpthsem20 2.0.8, it started to start without error?

wget https://www.auto.tuwien.ac.at/~mkoegler/debian/pool/main/p/pthsem/libpthsem20_2.0.8_i386.deb

So I guess it working now fine for me.
Thanks!!!

If I can test/do something to help, let me know!

on *my* system I was able to keep the libpthsem from the LinuxMCE deb repo.

Glad things are working!  I hope we can figure out what the issue is.

Each time I perform an apt upgrade, i'm having the same issue. 

I can "solve" it with:

Code Select Expand

wget https://www.auto.tuwien.ac.at/~mkoegler/debian/pool/main/p/pthsem/libpthsem20_2.0.8_i386.deb
dpkg -i libpthsem20_2.0.8_i386.deb

I've tried to follow the things that posde did, but I haven't got /etc/apt/preferences.
And when i run the apt reinstall, I'm getting the error

WARNING: The following packages cannot be authenticated!
  eibd-client-sources eibd-clients eibd-server libeibclient-dev libeibclient0
Authentication warning overridden.
E: Internal Error, No file name for lmce-eib-eibd:i386

When i do the apt-get update command, i'm getting

W: Failed to fetch http://ppa.launchpad.net/mkoegler/bcusdk/ubuntu/dists/trusty/main/binary-i386/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

ps I'm also getting other issues with the global apt-get upgrade. Not sure if it's related, but I mention it here, just in case... (forum-topic)
