我已经更新了 WSL 本身（以管理员身份）
> wsl --set-version ubuntu-20.04 2
> wsl --update
它有效但仍然不能解决我在 WSL Ubuntu 20.04 中的问题。

sudo rm -rf /var/lib/apt/lists/*也sudo apt clean没什么帮助。以下是我的资料来源，全部来自/etc/apt/sources.list。

我不知道这是否与 WSL 相关或与 Ubuntu 相关，但我猜是前者，因为我在原生 Ubuntu 上从未遇到过这样的问题。
我主要将 WSL 用作 SSH 和 Git 客户端。
有人知道这里出了什么问题吗？

如果你使用Acrons 真实形象. 感谢@jannes-bottis
按 Strg-Shift-Esc
转到“进程”选项卡，按名称排序并查找 Acronis Drive 进程。杀了它。
此后，更新有效。
@Acronis 请修复！
