Thought to document this to the forums as well. If you are trying to run Linux 1.64.144373, you will probably get an error like this:
./server: error while loading shared libraries: libsteam_api.so: cannot open shared object file: No such file or directory
This is caused by the server binary trying to search libraries from a folder named "RIGIN" for some unknown reason. Maybe Dwarden knows...?
steam@vide:~/arma2oa$ strace ./server -config=server.cfg 2>&1 | grep libsteam_api.so
...
openat(AT_FDCWD, "RIGIN/libsteam_api.so", O_RDONLY|O_LARGEFILE|O_CLOEXEC) = -1 ENOENT (No such file or directory)
I guess the easiest workaround for this would be to just create a folder RIGIN and copy/move all the libraries there, so that your folder/file structure looks like this:
steam@vide:~/arma2oa$ tree RIGIN
RIGIN
├── libsteam_api.so
├── libsteam.so
└── steamclient.so
