Install Deepin DE in Ubuntu 20.04: qtbase-abi-5-9-5 package

Update 20200515:

UbuntuDDE team has provided stable PPA. You can install packages from it:

sudo add-apt-repository ppa:ubuntudde-dev/stable
sudo apt-get install ubuntudde-dde

Tried to fix this in a fast way on VM, downloaded a dozen of deb-packages including libqt5core5a which provides qtbase-abi-5-9-5 and got serious dependency issue. Manual installation of packages from different releases may harm your system, so it is safer to revert these changes and to wait for packages with DDE specially prepared for 20.04 LTS.

Also I have searched the LaunchPad.net and found other PPA from Ubuntu DDE team - ppa:openarun/dde-dev. It allows to install DDE on Focal.

So you have to remove other PPA(s) by commands like:

sudo apt-get install ppa-purge
sudo ppa-purge ppa:leaeasy/dde

and add this PPA to the system

sudo add-apt-repository ppa:openarun/dde-dev
sudo apt-get install ubuntudde-*

and then it should work:

There is a stable UbuntuDDE release for focal fossa here: https://launchpad.net/~ubuntudde-dev/+archive/ubuntu/stable

Use:

sudo add-apt-repository ppa:ubuntudde-dev/stable
sudo apt-get update

I have tried it out on my focal installation successfully.

sudo add-apt-repository ppa:ubuntudde-dev/stable
sudo apt update
sudo apt install ubuntudde-dde
