LX steamcmd dumps core #496
Description
When trying to run steamcmd in a lx branded zone it segfaults when it tries to validate a game ( the game seems to be downloaded as the 100% implies but has not been written to the steam location yet)
How to reproduce
Install steamcmd in an ubuntu lxbranded zone ( I have not tested with other image)
https://developer.valvesoftware.com/wiki/SteamCMD#Ubuntu
Then try to install a game , in this case ark:
steamcmd +force_install_dir arkserver +login anonymous +app_update 376030 +quit
When the download reaches 100% it will dump core.
arkserver@ca47b8b6-5bde-466a-b5ff-6ddb472d15b2:~$ steamcmd +force_install_dir arkserver +login anonymous +app_update 376030 +quit
Redirecting stderr to '/home/arkserver/.steam/logs/stderr.txt'
Logging directory: '/home/arkserver/.steam/logs'
Looks like steam didn't shutdown cleanly, scheduling immediate update check
