How to prevent Ubuntu20.04 from sleeping.

[Arbeiter]

Hello,

Just got a fast Dell with Ubuntu20.04 for number crunching. But, the machine sleeps after maybe 10 minutes.

I looked into the web and applied these suggestions.

1-) sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

Did not work for me.

2-) I added a line in a file /etc/ssh/sshd_config

ClientAliveInteral 60 (I entered this line without that # at the beginning)

Did not work
One poster suggested using dconf-editor (but, not a Linux expert, so I did not).

Can anyone help??
Thanks
