W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/Release  Unable to find expected entry 'universe/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file)

E: Some index files failed to download. They have been ignored, or old ones used instead.

这是我第一次不得不面对这样的事情。

Answer 1

也有同样的问题。尝试了两件事：

sudo add-apt-repository ppa:kubuntu-ppa/backports

&

sude aptitude install kdelibs-bin kdelibs5-data kdelibs5-plugins

为我工作

Answer 2

安装前试着做：

sudo apt upgrade

对我来说很管用
