Unable to update or install Flatpak PPA

Been trying to add Flatpak Launchpad PPA as been documented, but it is not working for me on Ubuntu 22.04 LTS Pro, and it is not a network or internet connection issue. I receive this error when trying to add the PPA:

Here you go:

Advise to first verify connection to site:

$ ping launchpad.net
$ ping ppa.launchpadcontent.net


If no connection may try to disable IPv6.

Is there a reason flatpak package in the repo isn't working? PPA's can cause problems occasionally. Best to keep their use to a minimum.

I can however connect to the PPA via web browser:



I am going to try disabling IPv6 as suggested by Xian

[ianmoon]

@Xian , Thank you so very much!! You Rock!!

1. Disabled Ipv6:

daniel@dkdt:~$ sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
[sudo] password for daniel: 
net.ipv6.conf.all.disable_ipv6 = 1
daniel@dkdt:~$ sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6 = 1
daniel@dkdt:~$ sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1
net.ipv6.conf.lo.disable_ipv6 = 1

2. Added Flatpak PPA:

daniel@dkdt:~$ sudo add-apt-repository ppa:flatpak/stable
