pivpn/scripts/backup.sh
Orazio deee38b20e More safeguards, some fixes, standardized some code, WireGuard update script, removed redundant code
- Add curl as a dependency for those who run the script without 'curl URL | bash'.
  - Use POSIX 'command -v' instead of 'hash'.
  - Check if packages have actually been installed and abort execution if they have not.
  - Fixed issue with getStaticIPv4Settings() that prevented existing network settings
    to be used as static IP settings when running the script unattended with empty
    $IPv4addr and $IPv4gw variables.
  - Exit if processing wireguard-linux-compat fails.
  - Exit if 50unattended-upgrades fails to extract.
  - Exit clientSTAT.sh if the wg0 interface is not available.
  - Moved the Self Check to a single script since dedicated versions were very similar.
  - Add 'pivpn -wg' to update WireGuard for users running Raspbian with armv6l kernel.
