rename the 8bit CLI folder to 8bitCLI
then proceed with the GUI compilation-installation. Although after a few days the GUI crashes on linux as well (segmentation core dump)
In addition the config folder is hidden under the name .8bit on your home folder. Both the CLI and the GUI take their settings and blockchain data from .8bit folder (the same of appdata/roaming/8bit if you were on windows).
It return an error when I try to run 8bitd: "8bitd: error while loading shared libraries: libsecp256k1.so.0: cannot open shared object file: No such file or directory"
