apt broken in ubuntu/focal/cloud (amd64) about lxc-ci

[stgraber]

Hmm, odd. @monstermunchkin can you check that image?

[monstermunchkin]

Launching a container using lxc launch images:ubuntu/focal/cloud c2, and then running apt update inside of the container doesn't give me that error.

@marbetschar Does this happen every time? What are the exact steps to reproduce this issue?

@monstermunchkin it happens every time. Maybe my locally cached image is corrupt then? How do I force a redownload?

Steps to reproduce:

lxc launch images:ubuntu/focal/cloud focal-cloud-test
lxc exec focal-cloud-test -- su --login
root@focal-cloud-test:~# apt update

I did the exact same thing, and don't run into the error. My image's hash is 9c1933d418c3 (lxc image ls). You can run lxc image refresh <hash> (your hash) to update the image.

That fixed it. Thank you very much!!
