Any workarounds ?

[nobkd]

Sorry. I can't reproduce that.

Do you maybe have some software / proxy / ... interfering? Can you share OS / system / OPI version details? What was the command you tried to run? opi apache2?

Hi.

Sorry. I can't reproduce that.

Noted.

Do you maybe have some software / proxy / ... interfering?

There is a pfsense firewall. Outbound connections are allowed. Is there any specific port that needs attention ?

Can you share OS / system

What does curl -v https://opi-proxy.opensuse.org/ output? If you can reach it, it should return something like this:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>400 Bad Request</title>
<h1>Bad Request</h1>
<p>The browser (or proxy) sent a request that this server could not understand.</p>

So your filewall would need to allow https connections on port 443 to opi-proxy.opensuse.org

[marcoczen]

If you can reach it, it should return something like this:

Hi ... As below;

# nc -v opi-proxy.opensuse.org 443
nc: connect to opi-proxy.opensuse.org port 443 (tcp) failed: Connection refused
nc: connect to opi-proxy.opensuse.org port 443 (tcp) failed: Network is unreachable

# nc -v download.opensuse.org 443
Connection to download.opensuse.org 443 port [tcp/https] succeeded!

# nc -v google.com 443
Connection to google.com 443 port [tcp/https] succeeded!

Also;

# nmap -v -Pn -sS -sU opi-proxy.opensuse.org

Port 443 on opi-proxy.opensuse.org needs to be allowed, but that doesn't seem to work from your system.

It works for me, though. Both via IPv4 and IPv6.

Hi. I uninstalled and reinstalled opi. It doesnt show any errors now.

I ran opi apache2 and got a list of output. I havent figured out how to make it show info about each package and how to install though.

[asdil12]

just select the number of the entry you want as shown here:

[marcoczen]

Ok. Looks like I didnt get the lower portion of the output - back to the drawing board for me then .... Thanks mate !!! Closed
