运行时出现以下错误 sudo apt update

Aborted (core dumped)
Reading package lists... Done
E: Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/cache/app-info -a -e /usr/bin/appstreamcli; then appstreamcli refresh > /dev/null; fi'
E: Sub-process returned an error code

我该如何摆脱这个？

I am trying to enable WiFi. I tried sudo apt-get update. But I am getting this error:

The AppStream system cache was updated, but some errors were detected, which might lead to missing metadata. Refer to the verbose log for more information.

How can I complete sudo apt-get update and enable …

操作系统：16.04

自动升级后，apt-get update导致如下错误：

我发现这是应用程序流的错误，但我该如何修复它？

当我将 Ubuntu 从 16.04 更新到 18.04 时，出现大量错误：

$ sudo apt update && sudo apt upgrade

另外，当我检查我的 Ubuntu 版本时，它显示18.04在终端中，但在启动时它显示16.04. …

如果我没记错的话，我使用了sudo apt-get dist-upgrade，但我取消了中间的过程。我收到了(Y/N)升级到最后的提示，然后输入了 N。

在此之后，我在运行时遇到了一些这样的问题 apt-get update

有趣的是，我实际上运行的是 16.04。

Distributor ID: Ubuntu
Description:    Ubuntu 16.04.4 LTS
Release:    16.04
Codename:   xenial

但不知何故 apt-get 寻找artful包而不是那些用于xenial.

编辑：这就是我的/etc/apt/sources.list样子

我到处都用 xenial 替换了 artful，问题似乎已经解决了。
