How to use systemd-inhibit without sudo?

Question

I have an SBC (pine64) running Ubuntu 16_04 and I have a long process to do (build tensorflow). I'm using the nohup command to detach the process from my SSH session but two days consecutively my board rebooted at midnight. I saw that I can inhibit reboot, sleep and shutdown with systemd-inhibit.

Is there a way to use this command without sudo? Bazel build doesn't recognize my %JAVA_HOME when launched with sudo...

This is the command I'm trying to run:

systemd-inhibit --why="Compiling TF" nohup bazel build -c opt --copt="-funsafe-math-optimiza
tions" --copt="-ftree-vectorize" --copt="-fomit-frame-pointer" --verbose_failures tensorflow/tools/pip_package:build_pip_pa
ckage &

which gives me:

Failed to inhibit: Access denied

Any advice?

Maybe you can run ```systemd-inhibit sleep 100000``` in parallel with your build? — Scott - Слава Україні, Mar 11 '19 at 14:54
@Scott, I launched sudo `sudo systemd-inhibit sleep 518400` to be safe for 6 days and then run my build command without the systemd-inhibit. I still had to use sudo, is it normal? — Victor Meunier, Mar 11 '19 at 15:02
It seems reasonable that you would need to use `sudo` on a command that modifies the behavior of the system. — Scott - Слава Україні, Mar 11 '19 at 15:04
Yes ok seems reasonable. Also I used `sudo nohup systemd-inhibit sleep 518400` to detach the process from my SSH session. Thanks for your advice. — Victor Meunier, Mar 11 '19 at 15:17
The real question is why your board reboots at night? Have you configured it to reboot at specific times? — Daniel, Jan 27 '21 at 18:59

You can use systemd-inhibit --what=idle as a normal user to prevent the machine from suspending due to system idleness. Other locks require elevated privileges.
