Apt Mirror broken again?

Docker Engine General
1

I’m trying to follow https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository on an Nvidia Orin (arm64 Jetson) running Ubuntu 22.04. Running sudo apt update I get

E: Failed to fetch https://download.docker.com/linux/ubuntu/dists/jammy/stable/binary-arm64/Packages.bz2 File has unexpected size (81869 != 81267). Mirror sync in progress?
.

Google suggest that this is an issue with docker:

It is possible a sync was indeed in progress. I don’t know how it should work better, but I had this kind of problem with other APT repositories as well, like the default ubuntu package mirrors. If I try to apt update on an Ubuntu jammy now, where Docker CE repository is added, it works.

After a lunch break, apt update and sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin worked.
¯\_(ツ)_/¯
