Unable to open visual studio code in Ubuntu 20.04

I tried installing visual studio code by snap as well as apt in both cases it doesn’t work. refer to trace below after hitting code --verbose.

Other observations –

  1. It works with sudo code --user-data-dir its just not normal.
  2. When tried from apps->launcher icon blank window shows up.
  3. Does not seem to be issue with --disable-gpu faced by many people
A JavaScript error occurred in the main process

After digging internet for 4 to 6 hours found that issue was related to HOME environment variable which was wrongly set to /root changed it to /home/your_username and it worked.


  1. Open .bashrc file from /home/your_username (not /root)
  2. Add this to the last new line – export HOME=/home/your_username
  3. Restart computer or execute source .bashrc
