Hi Pierre,
You can follow the following steps:
-
Delete the location where you have unzipped the Postman app.
rm -rf /path/to/Postman
-
Delete the directory where all user data is stored (Warning!!! Any non-synced data will be lost forever, consider creating a backup first)
# Delete permanently rm -rf ~/.config/Postman # Or move as a backup (as a safer alternative) mv ~/.config/Postman ~/.config/Postman.old
