我只能这样做sudo apt-get update，其他任何事情都会给我带来错误。

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libplayerctl-dev : Depends: gir1.2-playerctl-2.0 (= 2.0.2-1) but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

答案1
问题似乎在输出中清楚地说明：
dpkg: error processing archive /var/cache/apt/archives/gir1.2-playerctl-2.0_2.0.2-1_amd64.deb (--unpack):
trying to overwrite '/usr/lib/x86_64-linux-gnu/girepository-1.0/Playerctl-2.0.typelib', which is also in package gir1.2-playerctl-1.0:amd64 2.0.2-1ubuntu1~ppa2
让我们详细分析一下：
dpkg: error processing archive X (--unpack):
trying to overwrite Y, which is also in package Z
X = /var/cache/apt/archives/gir1.2-playerctl-2.0_2.0.2-1_amd64.deb
Y = '/usr/lib/x86_64-linux-gnu/girepository-1.0/Playerctl-2.0.typelib'
Z = gir1.2-playerctl-1.0:amd64 2.0.2-1ubuntu1~ppa2
X 和 Z 都尝试提供文件 Y。在这种情况下，卸载包 Z 即可解决冲突。
sudo apt remove gir1.2-playerctl-1.0:amd64
