从 Ubuntu 16.04 升级到 18.04 后，几乎所有调用都会apt-get install导致此类错误......

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
texstudio : Depends: libpoppler-qt5-1 (>= 0.24.5) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
请注意，我在尝试安装的每个包上都会看到类似的内容。
我尝试了各种方法sudo apt-get -f install，sudo apt-get clean但都无济于事。我还删除了所有其他存储库，只剩下官方存储库。
那么，最大的问题是我是否已经毁掉了我的系统？
