AppImage doesn't work on Armbian 21.08.1 Focal

[MykolaMorhun]

I was trying to run mStream on my Linux server via AppImage, but it failed to run.

Steps to reproduce

1. Go to https://mstream.io/server
2. Get image for Linux Arm 32
3. Run downloaded mStream-Server-5.7.2-armv7l.AppImage

It fails with:

./mStream-Server-5.7.2-armv7l.AppImage: error while loading shared libraries: libz.so: cannot open shared object file: No such file or directory

System

$ cat /etc/os-release
