following the instructions on the official vpn page (instructions install openvpn client) in the second step:

curl -fsSL https://swupdate.openvpn.net/repos/openvpn-repo-pkg-key.pub | gpg --dearmor > /etc/apt/trusted.gpg.d/openvpn-repo-pkg-keyring.gpg

I get the following error message:

sudo curl -fsSL https://swupdate.openvpn.net/repos/openvpn-repo-pkg-key.pub | gpg --dearmor > /etc/apt/trusted.gpg.d/openvpn-repo-pkg-keyring.gpg -bash: /etc/apt/trusted.gpg.d/openvpn-repo-pkg-keyring.gpg: Permission denied (23) Failed writing body

Thanks in advance!!!
