I have downloaded nomadbsd to make a usb drive but cannot extract files. I am doing this on Linux Mint.
I have never tried any BSD prior to this. Any help would be appreciated.
I was using Linuxmint as well to extract the .img file from the .lzma zippered file. I just right-clicked on it, and from the right-hand menu chose “extract here”. The archive manager I used was installed, when I installed Linuxmint. I’m using Linux Mint 20.3 x86_64 Cinnamon Desktop. I see in the software repository there are numerous programs that can be installed. One of them might work too.
As well, on the Linuxmint website there is an extraction tool for .lzma files that can be installed too. See: https://community.linuxmint.com/software/view/lzma.
