Hello. I have encountered an issue while trying to set up Amnezia on a fresh Ubuntu server that didn't have the sudo command installed. The error message I received was misleading, indicating that the server port is already in use. However, the actual issue was the absence of the sudo command on the server.

To resolve this issue, I had to manually install sudo using apt install sudo.

Here are the logs from my session:

2023-08-19 21:26:12 info libpng warning: iCCP: known incorrect sRGB profile
2023-08-19 21:26:13 warning Qt Quick Layouts: Detected recursive rearrange. Aborting after two iterations.
...

2023-08-19 21:26:52 debug sudo lsof -i -P -n | grep -E ':27017 ' | grep -i tcp | grep LISTEN
2023-08-19 21:26:52 debug SSH chanel opened
2023-08-19 21:26:53 debug ServerController::runScript finished
2023-08-19 21:26:53 debug doInstallAction finished with code ErrorCode::5("Server port already used. Check for another software")

It would be helpful if Amnezia could handle this scenario better, either by providing a more accurate error message or by checking for the existence of sudo and installing it if necessary. I suppose the same for lsof and fuser.

Thank you.
