Python Scrips Keep Crashing at Install

Following the instructions, created an MS Hyper-V VM, brand new fresh install of Ubuntu 22.04Lts server.

Nothing extra installed, just the basics with SSH & Midnight Commander.

Every time I try to run : curl -s | sudo -E bash

I first get this crash:

FAILED: add-apt-repository -y ppa:duplicity-team/duplicity-release-git
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/httplib2/", line 1363, in _conn_request

    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):

Followed by this crash

During handling of the above exception, another exception occurred:

    raise ServerNotFoundError("Unable to find the server at %s" %
httplib2.error.ServerNotFoundError: Unable to find the server at api.launchpad.test

and then the set-up script just gives up and aborts.

I’ve got past the part that asks me for my email/IP address etc part, the values I see in there all seem ok to me, my internal and external domain names are all fully set up and working correctly from a DNS perspective.


Seems not to be resolvable

shawty@mbx:~$ ping api.launchpad.test
ping: api.launchpad.test: Name or service not known
shawty@mbx:~$ nslookup api.launchpad.test

** server can't find api.launchpad.test: NXDOMAIN


DNS resolution however is working correctly

shawty@mbx:~$ nslookup

Non-authoritative answer:
Address: 2a00:1450:4009:820::200e

So it doesn’t appear to be a DNS resolution error.

Any thoughts, or do I need to report this as a bug?

Many thanks

There have been some issues with ipv6 in this regard. If ipv6 is enabled, disable it and retry. If it is disabled, enable it and retry.

Ok, I’ll give that a try… thanks
