Yeah, it shouldn’t take more than a few minutes to install.
First, you may just want to try it again, to make sure it doesn’t work the second time around.
If it doesn’t work – you could try running “ps auxwf”, and then look for the install.sh process you ran from the command line. That command will show all processes, as well as all the child processes that were spawned.
When you find your install.sh process, what child processes were spawned that it’s waiting on?
