Edit:
I’ve been trying the steps in the manual but I can’t found the /etc/default directory so anyone knows what is happening or what might be the problem.
Thanks and sorry for not doing the question correctly at first
Yep, we have done this following that manual thing. If you do “cd //” can you see the etc directory? Or keep doing “cd ..” until you reach top directory then go down from there to find it 🙂
