Hi @shneuro, can I ask how much RAM your system has? You can find this out by running free -h in a terminal. It looks to me like one of the installation steps was killed by the OS, which usually means that it ran out of memory.
On an unrelated note, it also looks like there is a bug in the installer script which makes it incompatible with Python 2.7 - do you have a python3 command available on your system?
@paulmccarthy : I was able to get the installation to run successfully. I thoroughly studied your suggestions and ultimately, using the skip SSL option and throttle downloads option worked. Thank you again for being so helpful. Much appreciated!
Hmm, you have more than enough RAM, so something else is going wrong. What version of Rocky are you using?
In any case, I have made some more changes to the fslinstaller.py script - could you try downloading the latest version (3.16.5) and trying to run it like this?
