## Troubleshooting

### GPG Signature Error

```
Failed to verify signature archive-contents.sig:
No public key for 066DAFCB81E42C40
```

#### Method 1: Import GPG Key

```bash
gpg --homedir ~/.emacs.d/elpa/gnupg --receive-keys 066DAFCB81E42C40
```

#### Method 2: Disable Signature Check (Temporary)

```bash
# Disable signature check
sed -i "s|(setq package-check-signature 'allow-unsigned)|(setq package-check-signature nil)|g" \
  "$HOME/.emacs.d/init.el"

# Inside Emacs
M-x package-install RET gnu-elpa-keyring-update RET

# Re-enable signature check
sed -i "s|(setq package-check-signature nil)|(setq package-check-signature 'allow-unsigned)|g" \
  "$HOME/.emacs.d/init.el"
```

### Package Installation Issues

If packages fail to install, try:

```elisp
M-x package-refresh-contents
M-x package-reinstall RET <package-name> RET
```

### Font Issues

If fonts don't render correctly:

1. Install fonts: `M-x all-the-icons-install-fonts`
2. Restart Emacs
3. Check available fonts: `M-x font-selector`
