我正在尝试在 WSL 上升级 Ubuntu，但无法获取 dpkg 包并尝试打开 /ver/lib/dpkg 中的文件状态。该文件存在。
我已经尝试了所有我能找到的补救措施：
sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get --fix-missing install
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get clean
sudo apt-get autoremove
sudo dpkg --clear-avail && sudo apt-get update
sudo dpkg--configure-a
dpkg: error: failed to open package info file '/var/lib/dpkg/status' for reading: No such file or directory
$ ll /var/lib/dpkg/

重新安装不起作用。
我之前在 PC 上安装过 Ubuntu，现在其他发行版也能用。这台机器上的 apt 进程坏了，我不知道该怎么修复。
