I thought that I had this problem, until I realised that I hadn't tried the systemctl stuff mentioned above. FYI The following command resolved the issue for me:
sudo systemctl mask sleep.target suspend.target hibernate.target hybrid- sleep.target -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1874639 Title: desktop pcs start to suspend by default Status in linux package in Ubuntu: Confirmed Bug description: after the kernel upgrade our office desktops started to suspend after inactivity and with users logged out. this is rather unacceptable since we also use the pcs to run computational jobs. i tried to prevent the suspension via systemctl but the sleep.target, suspend.target, hibernate.target, and hybrid-sleep.target don't exist anyway... how to prevent this from happening?
