Got this error when starting it, please have a look at these screenshot.
I'm definitely not a Ubuntu expert but searching is something i can do!
I did follow the few instruction given, installed cuda 11.4, extract the folder, edit the file and try to start it.


Thanks!
the bash scripts are in windows format with CR/LF end of line, but linux uses only LF
you can use dos2unix to convert these files :
dos2unix tbminer_ethermine_eth.sh
if you want to save the output in different file :
dos2unix -n tbminer_ethermine_eth.sh corrected.sh
