当我尝试安装新软件时，该过程中断dpkg并libllvm12出现以下错误：
The following packages have mismatched dependencies:
libllvm12 : Break: libllvm12:i386 (!= 1:12.0.0-3ubuntu1~20.04.3) but 1:12.0.0-3ubuntu1~20.04.4 is installed libllvm12:i386 : Break: libllvm12 (!= 1:12.0.0-3ubuntu1~20.04.4) but 1:12.0.0-3ubuntu1~20.04.3 is installed
E: Mismatched dependencies. Try 'apt --fix-broken install' without any packages (or specify a solution)
也sudo apt --fix-broken install不起作用，因为dpkg出现错误：
dpkg-deb: error: subprocess <decompression> returned exit status 2
error dpkg: error processing file /var/cache/apt/archives/libllvm12_1%3a12.0.0-3 ubuntu1~20.04.4_amd64.deb (--unpack):

此外，Ubuntu 商店已损坏，只有文本，齿轮图标，并且无法找到屏幕截图。
