Curious: Upgrade the stable version kUbuntu13.10 to kubuntu14.04. The result is a waste of two days of fixing the system, one by one!

Downgrading ....

Kubuntu14.04-> kubuntu13.10

1) Find the code of the two systems: saucy (13.10) | trusty (14.04)

 

2) modify the/etc/apt/sources. list file and put it in only two rows (note that the font content with the same color is consistent)

Deb http://archive.ubuntu.com/ubuntu saucy main restricted universe multiverse
Deb http://archive.ubuntu.com/ubuntu trusty main restricted universe multiverse

 

3) modify or add the/etc/apt/preferences file and only fill in the following content:

Package :*
Pin: release a = saucy
Pin-Priority: 1001

Package :*
Pin: release a = trusty
Pin-Priority: 60

 

4) sudo apt-get update

5) sudo apt-get dist-upgrade

6) restart the instance.

 

Note: The method for downgrading other Debian versions is similar.
