Need help with paperless-ngx script

[BerndR329]

I tried to install paperless ngx on my proxmox server with that script: bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/paperless-ngx.sh)"

The installation does not work. It ends with the error message:
`curl: (6) Could not resolve host: raw.githubusercontent.com
/dev/fd/63: line 1: $'\E[?25h': command not found

[ERROR] in line 1: exit code 0: while executing command
0: line 14: pop_var_context: head of shell_variables not a function context

[ERROR] in line 1185: exit code 0: while executing command lxc-attach -n "$CTID" -- bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/install/"$var_install".sh)" $?`

Unfortunately I have no experience with proxmox. Could anyone please help me?

Best regards
Bernd
