Fixing the upower warning - WSL/ZSH/Spaceship prompt

December 11, 2020

The blog post discusses a warning that appears when using the Spaceship prompt in Windows Subsystem for Linux (WSL) with ZSH:

(upower:26251): UPower-WARNING **: 10:47:25.757: Cannot connect to upowerd: Could not connect: No such file or directory

The author provides a solution to disable the battery status feature in the Spaceship prompt:

# Turn off power status when using spaceship prompt
export SPACESHIP_BATTERY_SHOW=false

This can be added to the ~/.profile file to prevent the upower warning from appearing.

Key Takeaways

• The warning occurs because upowerd is not running in WSL
• Disabling the battery status feature resolves the issue
• The fix can be implemented by setting an environment variable
