This is still an issue after 1.70 release today.
It seems like Linux dedicated servers are not working at all.

openSUSE 13.2 "Harlequin" x64
kernel: 3.16.7-53-desktop
Same segmentation fault issue as above.

This is awful and has to be hotfixed asap.

I can confirm the issue on a freshly installed Arma 3 Linux server and an existing server with and without mods.

Ubuntu 16.04.2 LTS
kernel: 4.4.0-59-generic

Confirm the same on openSuse Leap 42.2 x64

And there it is again.. Another non-minor issue that was known well before release and it still got released and now we are doomed till BI does something.

I will include the release version in the title too then.

Based on this information I was able to do so:

cd /home/steam/steamcmd
cp linux32/steamclient.so arma3

work for me !

work for me too, thank you !

this workaround lets the server start without crashing but trying to connect kicks me off saying that steam authentication failed.

My guess is the server has no connection to the steam servers to auth people

Confirm, this fixed issue for me too, Thanks a lot!
However, I have x64 linux system so I did:

rm /path/to/arma3/steamclient.so
ln -s /home/steam/steamcmd/linux64/steamclient.so /path/to/arma3/steamclient.so

Thanks! This is working for me also.

In case a bit more detail would help anyone else, rename or delete the current steamclient.so in the Arma server directory and replace it with a copy or symlink (preferable) to the one provided by steamcmd. In the case of LGSM setups, this looks like:

cd /home/arma3server/serverfiles
mv steamclient.so steamclient.so.bak
ln -s ../steamcmd/linux32/steamclient.so

It's just a warning, not error. I had this message on every start before v1.70 update and server works fine.

Ignore my comment above. Using the shortcut worked wonders. Though you'd have to use the x86 version of steam afaik. Arma doesn't speak to the x64 steamclient

it works! thank you a lot

My script kept replacing the steamclient.so when I restarted by doing another update :( So now I do the ln in the shellscript before launch but after version check. All is good now, thanks :)

Doublechecked it. Clients can connect and play on server without a problems.

fixed it for me either.

Also confirming that it works, thanks. Just make sure to use the 'linux32/steamclient.so' version.

Thanks it works! I will mary You <3 :D

My server starts successfully, even though I have some new minor issues that didn't exist before the DLC update ...

I can also confirm sym linking the steamclient.so from the linux32 directory worked for me.

I am running Debian 8 this also fixed it for me:

cd /home/arma3server/serverfiles
mv steamclient.so steamclient.so.bak
ln -s ../steamcmd/linux32/steamclient.so

Thx guys! Hopefully BI will release something quick to fix that.

Of course we are expecting a definitive solution from Boehmia, but we know that linux users are always left last in the priorities

I can confirm the symlink fixed it on CentOS 7.

Symlink or copying isn't a FIX it's just a temporary prothesis to just run a server. My community has major problem, because right now we can't play missions including DAC, after update they cant generate waypoints - on windows server there is no such problem

Supposed to be fixed on dev branch according to the changelog.

Fixed: Linux Dedicated Server was refusing to start (https://feedback.bistudio.com/T124761)

After the Hotfix update it still works for me. So that apparently has the correct files in it now.
