描述

Describe the bug I am encountering the following error when trying to launch an image too quickly after installing Multipass.

launch failed: Remote "release" is unknown or unreachable. If image mirror is enabled, please confirm it is valid.

This is occurring on a self-hosted Github runner that supports nested virtualisation.

To Reproduce How, and what happened?

  1. sudo snap install multipass``multipass ...
  2. multipass launch 16.04 --name test

When adding a 10s delay between steps 1 and 2 the issue does not occur.

Expected behavior For the image to be able to launch after the snap install was completed.

研究方向
Investigate the timing issue between snap install and the first launch. Check how the remote 'release' is set up during installation. Look at related code in the Multipass repository, possibly in the launch or image retrieval modules. The comments suggest a race condition; consider adding a delay or ensuring the remote is fully initialized before allowing launch.
