Linux is our labour of love.
Starting with build 114220 we have upgraded our Ubuntu based toolchain to gcc-9 with LTO which is available in the default repositories or backports of most distributions.
gcc-9 is available for all Ubuntu releases back to Ubuntu 12 Precise and derivatives via https://wiki.ubuntu.com/ToolChain
gcc-9 for Debian 10 buster can be pulled from Debian 11 Bullseye.
https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html
Local servers will see performance improvements from the move to gcc-9 with LTO and c++17.

Linux Dependencies
- libstdc++6 >= gcc-9 GLIBCXX_3.4.26 (native)
- libcurl4-gnutls or libcurl-compat (native on non Ubuntu / Debian)
- libsdl2 (provided by steam)
- libgl1 (provided by steam)
- libudev0 (provided by steam)
- libuuid (provided by steam)
There are some known issues for Linux distributions not based on Ubuntu / Debian.
As a last resort if packages are not available for libudev0 or libcurl4-gnutls you might be able to use a hacky symlink (not recommended).
Stops on launch splash
Downloads are stalled due to missing certs on some non Debian / Ubuntu distributions like Fedora or NixOS.
Use the OpenSSL SSL_CERT_FILE environment variable when launching PA from a shell script:
SSL_CERT_FILE=/etc/ssl/certs/ca-bundle.crt
For steam command line arguments use:
SSL_CERT_FILE=/etc/ssl/certs/ca-bundle.crt %command%
Black screen or fails to start
Check your logs for missing dependencies:
- libcurl4-gnutls
- libstdc++6 from gcc-9 or newer
Some non Ubuntu / Debian distributions provide a libcurl-compat package for compatibility with libcurl-gnutls from Ubuntu based builds.
