I am a complete amateur in Linux.

There is a software that only runs on Linux. It came with a virtual machine package and every thing.

When inside the virtual machine, I run a .py file in the terminal and it starts downloading the software. The software file is quite large. I noticed every time I let the software to download, the installation wants to start and asks me for the password. I am usually not there to enter and it fails.

I wanted to see how I can get over this problem. Thanks

  • Unless you give us the name of the software, there's not much we can do.
