Share a solution to the problem that Ubuntu cannot be accessed normally using ssh because KDE is not installed correctly.

1. About the version of the linux environment

I just installed ubuntu

The version information is as follows

Linux version 4.4.0-78-generic (buildd@lgw01-11) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4) )

You can also type on the linux command line cat /proc/versionCheck your own linux version

2. About the phenomenon and solutions to this problem

Phenomena 1//

Just a few days after installation, an error dialog box will pop up after booting up. I sent an error report to the official website and was recommended several patches to fix the bug but it was not solved. Question

And because I thought this error report had no impact on me at first, I decided to ignore it

For those who are new to ubuntu I don’t know what KDE is. Since this is not the focus, I will put the introduction to KDE at the end of the article

Phenomenon 2//

When I was studying, I needed to use the root user to access port 22 of my Linux, which is the ssh service. When I was going to modify the /etc/ssh/sshd_config file, I found that I did not have this file at all

Phenomena 3//

When I checked online later, netizens said that there was no such file, maybe openssh-server was not installed correctly (the original URL to solve this problem ), so I issued the command to reinstall it and got an error!

The specific error is as follows:

What is KDE again! Very good, you successfully attracted my attention

Solution 4//

Finally, I directly searched for KDE installation failure and found out A useful post (Website 1:; Website 2:+bug/1451728)

It turns out that this bug may be caused by file conflicts during program installation

Consider First use sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade to update all software packages. After updating, I still get an installation error

So I use a direct forced override:apt-get -o Dpkg::Options::="--force-overwrite" -f install

Finally, my KDE did not report an error, and the openssh service may be installed normally. Yes, but someone in the post said that the telepathy account may not work properly, let’s use this first
