I still get the failure. From the prompt in your run, it looks like you are running the arm64 version, i am running the armhf version. That seems unlikely to be significant difference, but there are at least some major differences since the arm64 cannot use the usb ports on the pi 4b with 4GB and that is what I have.
i do have outside connectivity. shire:~(20) ping www.ubuntu.com PING www.ubuntu.com (91.189.89.115) 56(84) bytes of data. 64 bytes from www-ubuntu-com.privet.canonical.com (91.189.89.115): icmp_seq=1 ttl=56 time=85.1 ms 64 bytes from www-ubuntu-com.privet.canonical.com (91.189.89.115): icmp_seq=2 ttl=56 time=78.5 ms 64 bytes from www-ubuntu-com.privet.canonical.com (91.189.89.115): icmp_seq=3 ttl=56 time=79.2 ms ^C -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to software-properties in Ubuntu. https://bugs.launchpad.net/bugs/1849714 Title: failure to install repos for raspberry pi Status in software-properties package in Ubuntu: Incomplete Bug description: following the directions about 1/5 down the page of https://wiki.ubuntu.com/ARM/RaspberryPi sudo add-apt-repository ppa:ubuntu-raspi2/ppa Cannot add PPA: 'ppa:~ubuntu-raspi2/ubuntu/ppa'.
