当我尝试安装 VLC 时 # dnf install vlc，出现以下错误：
Error:
Problem: package vlc-1:3.0.16-1.fc34.x86_64 requires vlc-core(x86-64) = 1:3.0.16-1.fc34, but none of the providers can be installed

(try to add '--skip-broken' to skip uninstallable packages)
我不明白为什么它说相互冲突的请求
然后我尝试手动安装依赖项：
# dnf deplist vlc
并得到：

我安装了它们中的每一个，但仍然收到第一个错误。
（我尝试在另一台 Fedora 34 上安装 VLC，但没有收到这些错误，并且安装成功并且工作正常，没有任何问题。）
有谁知道为什么吗？？
