dell-linux-assistant/bionic 2.2.0545 amd64 [upgradable from: 2.2.0544]
dell-linux-assistant/now 2.2.0544 amd64 [installed,upgradable to: 2.2.0545]
我认为这个pb来自于我的实际20.04.1来自于升级18.04！
请注意，获得此升级太不可能了：20.04.2
根据@NOrbert 的要求
jrd_10@my-pc:~$ sudo apt-cache policy dell-linux-assistant
dell-linux-assistant:
Installed: 2.2.0544
Candidate: 2.2.0545
Version table:
2.2.0545 500

我通过添加新的 ppa 解决了这个问题“萨默维尔-dla 团队”为了焦点变体。
在终端中：
sudo add-apt-repository ppa:somerville-dla-team/ppa
并通过软件和更新（GUI）停用旧的 ppa somerville-dla-team/ppa/ubuntu bionic main。
之后在终端中：
sudo apt update && sudo apt full-upgrade
就我的情况而言，结果是：
Er moeten 397 kB aan archieven opgehaald worden.
Na deze bewerking zal er 1.024 B extra schijfruimte gebruikt worden.

我必须重新启动笔记本电脑（Dell XPS-13-9310）才能运行戴尔助手。
