我正在尝试按照说明将我的 WSL 1 Ubunutu (18.04) 版本升级到 WSL 2 Ubuntu-20.04，但第一步出现了一条错误消息，我不知道如何解决。
wsl --set-version ubuntu
Conversion in progress, this may take a few minutes...
For information on key differences with WSL 2 please visit https://aka.ms/wsl2
Exporting the distribution failed.
bsdtar: Couldn't read link data: I/O error
bsdtar: Error exit delayed from previous errors.
我也尝试过以“正常”的 Ubuntu 方式进行操作，但得到了不同的“错误”：
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.5 LTS
Release: 18.04
Codename: bionic
