Cannot install jitsi, Ubuntu

connection timed out on download.jitsi.org:443

today still the same problem. Can someone reach out or intervene to solve it?

Reachable for me

don’t attempt to specify a http scheme to connect to port 443, it’s dedicated to https.

this doesn’t help much. Still unreachable here.

I am using https.

well, the link you posted is using http and port 443.

deb [signed-by=/usr/share/keyrings/jitsi-keyring.gpg] https://download.jitsi.org stable/

this is the link in jitsi-stable.list. Still unreachable.

what gives
sudo apt update --print-uris | grep jitsi

and what gives a curl on the first result (if you get one)

apt update --print-uris | grep jitsi

I get a warning ‘new users can only put 2 links in a message’ so the rest is truncated.

curl just blocks indefinitely.

that’s a problem in your network path:

what gives just

DNS all right, it looks like a firewall problem, or you are in a country doing some blocking.

I don’t think, I am in Italy and everything is accessible. My firewall accepts all links so either I don’t think it’s a firewall problem.

Is wget working

wget -O - https://download.jitsi.org/stable/InRelease

and the output for this one?

curl -vvv https://download.jitsi.org/stable/InRelease

Is there an http proxy in your network?

No.
If you can’t resolve the issue I will have to download packages with my browser and do a manual install, but I would like to avoid this.

Since this issue is special for you, you can do whatever you want

I just downloaded all the most recent packages with my browser, so I don’t think the issue is special for me. Probably you can revise from your side, as by reading the forum I notice that this is not the first time this issue happens, and I am not the first user suffering it.
