Tips

WSLでUbuntu 22.04 LTS実行し、インストールやアップグレードを行うと下記のようなエラーが出ることがあります。

Scanning linux images...

Failed to retrieve available kernel versions.

Failed to check for processor microcode upgrades.

No services need to be restarted.

No containers need to be restarted.

User sessions running outdated binaries:
root @ /dev/pts/0: apt[399,1563]

No VM guests are running outdated hypervisor (qemu) binaries on this host.

何でしょうねこれ。Kernel?マイクロコード?

WSL2の仕様の問題のようです。
