I got these errors when following the quick-installation process.
Errors were encountered while processing: jitsi-meet-prosody jitsi-meet jitsi-meet-turnserver E: Sub-process /usr/bin/dpkg returned an error code (1)
There were quite a few errors before that if needed I can add as well.
When I direct the browser to my IP address I get the standard:
Welcome to nginx!
If you see this page, the nginx web server is successfully installed and working. Further configuration is required.
