🚨 Troubleshooting

Common Issues

Externally-Managed-Environment Error

# Error: externally-managed-environment
# Solution 1: Use pipx (recommended)
sudo apt install pipx
pipx install ufm-config-diff

# Solution 2: Use virtual environment
python3 -m venv venv
source venv/bin/activate
pip install ufm-config-diff

# Solution 3: Override system protection (advanced users only)
pip install ufm-config-diff --break-system-packages

Docker Permission Denied

sudo usermod -aG docker $USER
# Log out and log back in

Port Already in Use

# Check what's using UFM ports
sudo netstat -tulpn | grep -E ':(80|443|8000|6306|8005|8888|2022)\s'

UFM Already Installed

# The tool will automatically detect and offer to uninstall
# Or use --yes flag for automatic handling
ufm-config-diff old.gz new.gz license.lic --yes

Email Not Sending

# Set SMTP server environment variable
export SMTP_SERVER=your-smtp-server.com
ufm-config-diff old.gz new.gz license.lic --email [e-mail]

Command Not Found After Installation

# If installed with pipx, ensure pipx bin directory is in PATH
pipx ensurepath

# If installed in virtual environment, make sure it's activated
source venv/bin/activate

# If installed system-wide, try:
which ufm-config-diff
