最近一两个月，全新安装的 Tumbleweed 系统会具有一个奇怪的依赖项：busybox-which。
它会在安装某些应用时，引起冲突，例如：
env LANG=C sudo zypper install simple-scan
Loading repository data...
Reading installed packages...
Resolving package dependencies...
Problem: the to be installed simple-scan-44.0-1.1.x86_64 requires 'xdg-utils', but this requirement cannot be provided
not installable providers: xdg-utils-1.1.3+20210805-2.2.noarch[repo-oss]
Solution 1: deinstallation of busybox-which-1.36.0-26.2.noarch
Solution 2: do not install simple-scan-44.0-1.1.x86_64
Solution 3: break simple-scan-44.0-1.1.x86_64 by ignoring some of its dependencies
这个软件包似乎还会导致 YaST 组件无法正常启动。
解决方案如下：
sudo zypper install which
