Installing MIAB v61.1 on Ubuntu 22.04 (Hostinger VPS 1)

Yes, MIAB installation script reports both my IPv6 address and my IPv4 address.
However, the installer suddenly stops and returns to the command prompt at the random number generator.

Do you know where the MIAB installation log files are stored? I can check the log files and paste them here, and hopefully someone can tell us what went wrong?
