  warning: could not trust CA: update-ca-certificates: No such file or directory (os error 2)
  HTTPS proxy will work but browsers will show certificate warnings.

On Arch Linux, the CA trust mechanism differs from Debian-based distributions.

The application currently relies on the update-ca-certificates command to install or refresh trusted Certificate Authorities. However, this command is not guaranteed to exist on Arch Linux systems, especially in minimal installations.

Instead, Arch Linux uses the p11-kit based trust system, where certificate management is handled via the trust command.
