📝 Provide a clear and concise description of the issue.

Running update inside a Pingvin Share LXC leads to this error:

    ____  _                   _     
   / __ \(_)___  ____ __   __(_)___ 
  / /_/ / / __ \/ __ `/ | / / / __ \
 / ____/ / / / / /_/ /| |/ / / / / /
/_/   /_/_/ /_/\__, / |___/_/_/ /_/ 
              /____/                

environment: line 37: pingvin_version: unbound variable

The problem is that line 37 looks for a "$pingvin_version.txt" variable that doesn't exist, while it should look for a file named "pingvin_version.txt".
