今天早上進行軟體包更新時，我得到了這些軟體包將被刪除的資訊：
- 等離子發現
- 等離子發現快照後端
- ubuntu-發布-升級程式-qt
無法準確告訴您最近更新了哪些軟體包（甚至不知道如何檢查）。
不管怎樣，我說，「是的，更新需要什麼。如果我以後需要這些，我會再次安裝它們」。
但是，現在它不允許我在嘗試修復它時安裝具有以下依賴項問題的plasma-discover：
~ » sudo apt-get install plasma-discover

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:
The following packages have unmet dependencies.
plasma-discover : Depends: ubuntu-release-upgrader-qt but it is not going to be installed
Recommends: software-properties-kde but it is not going to be installed

software-properties-kde : Depends: python3-software-properties (= 0.96.24.32.1) but 0.96.24.32.3 is to be installed

python3-software-properties is already the newest version (0.96.24.32.3).
The following packages were automatically installed and are no longer required:
libamd2 libbabl-0.1-0 libcamd2 libccolamd2 libcholmod3 libgegl-0.3-0 libmetis5 libsnapd-glib1 libsnapd-qt1
libumfpack5
Use 'sudo apt autoremove' to remove them.
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
現在我真的不知道這是否是我所做的事情的問題，或者只是一個依賴問題，我必須等待解決。
我將不勝感激任何建議。 Plasma Discover 可以回到我的 KDE 嗎？
乾杯!
