I'm a dev, you are absolutely right, they could have make it so depending on option used the right libraries would load or not... instead of blindly loading everything at start and then chose what to use depending on the options....

If this new release isn't compatible with 18.04, then I can't continue running it on my server because it's older hardware that won't play nicely with 20.04. It runs everything - including Valheim - fine without this change. This isn't cool.

SO....Use the beta branch? (Old_Valheim) Problem solved...

I feel you... They need to do a patch and not load that crappy PlayFab when not using the argument -crossplay

Same here. VH server was running fine for ages on a Ubuntu 18.04 server. This update killed it. I don't want to use crossplay. I just want the Valheim server to work again. I can't just upgrade Ubuntu willy-nilly as that server hosts a load of other stuff.

I'm not a dev dude, but isn't there an option to package stuff on Linux so it comes with the necessary dependencies included, and becomes more or less distro-agnostic?

Thank you for your reply. I will try to open a support ticket.

If there is anyone wondering what the issue is in the log:

Caught fatal signal - signo:11 code:1 errno:0 addr:0x50

Seems to be related with Unity packaging running on Ubuntu when using mono.
I find this curious. I let anyone knows if I get it fix ( and how of course ).

Segmentation fault

They are using a new libparty.so library for Xbox FabParty which it seems does not support older versions of Linux distro's. I know ubuntu 18.04 you get a segmentation fault. Upgrade your server to 20.04 or above and it should be fine.

So it happened to be an Issue with PreFab not being compatible with all Ubuntu version.

( PreFab is what they use to have the crossplay activated when not using Steamwork ).

Updating Ubuntu to its latest version seems to be the work around.

I'm not interested to use PlayFab but it seems to not give you the choice... it would just seg fault at start, with or without it.

Hi Kanopy,

I just saw your post on the other section, thank you for your message here.

Note: My issue is I can't afford to loose everything on my server just for Valheim server.
They should have keep compatibility when not running with PlayFab... seems they load it anyway ( even if not used ) disregarding the command option.

I will try to see what I can do.

If this new release isn't compatible with 18.04, then I can't continue running it on my server because it's older hardware that won't play nicely with 20.04. It runs everything - including Valheim - fine without this change. This isn't cool.

Tested mine. Using LinuxGSM. No issues so far.
Maybe get the server logs and put in a support ticket
