Linux CLI - System Administration
You run systemctl enable myservice but get an error saying 'Failed to enable unit: Unit file myservice.service does not exist.' What is the most likely cause?
AYou need to run the command as a normal user, not root
BThe systemctl command is not installed
CThe service is already enabled, so enabling again causes error
DThe service file myservice.service is missing or not installed
Step-by-Step Solution
Solution:
Step 1: Analyze the error message
The error says the unit file does not exist, meaning systemd cannot find the service definition.
Step 2: Check other options
Running as root is required, but error is about missing file, not permissions. Already enabled services do not cause this error. systemctl is present.
Final Answer:
The service file myservice.service is missing or not installed -> Option D
Quick Check:
Missing unit file causes 'does not exist' error [OK]
Quick Trick:Missing service file causes 'does not exist' error [OK]
Common Mistakes:
Running as normal user instead of root
Assuming service is already enabled
Thinking systemctl is missing
