Fix CS.GO lib problem in Ubuntu 21.10

FixCS.GOinUbuntu21.10.txt

# After upgrading Ubuntu to 21.10 CS.GO in Steam for Linux stopped working
# (@see https://github.com/ValveSoftware/csgo-osx-linux/issues/2815
#  and https://github.com/ValveSoftware/csgo-osx-linux/issues/2811
# )

# Here is how I fixed it:

# 0) Exit Steam, make sure it is not running anymore
$ ps aux | grep steam

# 1) download correct lib debian package:
$ apt download libtcmalloc-minimal4

# 2) extract that package (no need to install it!):
$ ar vx libtcmalloc-minimal4_2.9.1-0ubuntu2_amd64.deb

# 3) (optional) make a backup of the steam installed version of lib file
$ cd ~/.local/share/Steam/steamapps/common/Counter-Strike Global Offensive/bin/linux64
$ mv libtcmalloc_minimal.so.0 libtcmalloc_minimal.so.0.orig-steam

# 4) copy the lib from extracted deb package to steam folder
$ cp PATH_OF_EXTRACTED_DEBIAN_PACKAGE/libtcmalloc_minimal.so.4.5.9 ~/.local/share/Steam/steamapps/common/Counter-Strike Global Offensive/bin/linux64/libtcmalloc_minimal.so.0

# 5) Start Steam and enjoy your CS.GO again :)

Those commands doesn't work for me, it says "command not found".

Useless.
