| tuned expects python2 as its intepreter. the script does not specify the python version and it installs all of the modules are installed in /usr/lib/python2.7/. If you have python3 installed, the service will fail to start because python3 does not have the *tuned* module dependencies. The sanest solution that should survive upgrades and changes to tuned python, is to give the systemd service the correct python environment in which to execute via override. Until, of course, tuned gets ported to python3. | |
| tested with tuned 2.9.0-1 in ubuntu 18.04 | |
| 1. sudo apt-get install tuned | |
| 2. sudo systemctl edit tuned | |
| [Service] | |
| Environment=PYTHONHOME=/usr/lib/python2 | |
| Environment=PYTHONEXECUTABLE=/usr/bin/python2 | |
| Save it | |
| 3. sudo daemon-reload | |
| 4. sudo restart tuned | |
