Unable to run from apptainer template because apptainer PPA missing

^{Originally posted by **thillerson** September 22, 2024}
I'm trying to run an Apptainer instance, but the standard template ([here](https://github.com/lima-vm/lima/blob/master/examples/apptainer.yaml)) seems to be failing during the Apptainer installation.

If I `sudo su` and look at the logs in `/var/log/cloud-init-output.log`, I see this error:
```
+ add-apt-repository -y ppa:apptainer/ppa
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/httplib2/__init__.py", line 1343, in _conn_request
conn.connect()
File "/usr/lib/python3/dist-packages/httplib2/__init__.py", line 1119, in connect
address_info = socket.getaddrinfo(host, port, 0, socket.SOCK_STREAM)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/lib/python3.12/socket.py", line 963, in getaddrinfo
for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
socket.gaierror: [Errno -3] Temporary failure in name resolution
```

And at the end: `Unable to find the server at api.launchpad.net`.

It seems clear that the repo isn't in some kind of registry, but I'm not clear on what to do next... any guidance?
