If you install Python etc. in a Libertine container, it cant be accessed from the host system. I guess thats why when I try to use the script, it fails to install the dependencies.

@lakotaubp yes

I want to use a VPN (I tried OVPN and Torguard) on my Pixel 3a with UT but I cant get it to work, since the official tutorial uses other files than the ones I have. I get the Files "ovpn-ca.crt", "ovpn.conf", "ovpn-tls.key" and "update-resolv-conf" from my VPN provider. But the tutorial uses other Files. The .ovpn file also looks like this, which is nothing like in the tutorial.

client
dev tun
proto udp
remote vpnserver 501
remote-cert-tls server
auth SHA256
key-direction 1
setenv CLIENT_CERT 0
<tls-crypt>
-----BEGIN OpenVPN Static key V1-----
RANDOM TEXT
-----END OpenVPN Static key V1-----
</tls-crypt>
resolv-retry infinite
nobind
cipher AES-256-GCM
auth-user-pass
compress
ncp-disable
tun-mtu-extra 32
<ca>
-----BEGIN CERTIFICATE-----
RANDOM TEXT
-----END CERTIFICATE-----

EDIT: What happens is, that it times out.
