Wrong Icons Theme, Sounds and Main Theme after Upgrade from 18.04 LTS to 20.04 LTS

I upgraded today my PC from 18.04 LTS to 20.04 LTS and get some visual issues. After upgrading I don’t get the new Icons Theme, System Sounds and Main Theme from 20.04 LTS. It’s the Adwaita Theme and Icons Theme. I had still Gnome Tweaks installed and tried to change it by hand to the new theme but I see any new. I got still all basic themes from 18.04 LTS. It’s the same with the icons and system sounds. But the strange is it don’t got any errors.

I Googled a bit but found not any usable solutions. I already tried sudo update-icon-caches /usr/share/icons/*and sudo gtk-update-icon-cachebut both without any effect. I don’t know which log I have to show you but I hope main.log from /var/log/dist-upgrade is the right one. Here to the log: https://gist.github.com/Johnnii360/f9bb612cdce409afb59aa7c5a0acc574

Ah and btw. I also don’t see any icons on desktop anymore.

Just a small info:

johannes@johannes:~$ cat /etc/lsb-release

Here a list of all my installed packages: https://gist.github.com/Johnnii360/4b5fe2abb25e1d010b2eb9935b41af6f

I also run updates but nothing new. It’s like there is also some missing – maybe. I upgraded the Notebooks from my Mother yesterday without any issues. Is there maybe some config file I have to show you?

Ah and I always get this updates here but if I try to update it won’t:

Appendix:
The icon from the Software Center (Ubuntu) is still the generic one. I also had installed the Gamemode but don’t get the icon in the shell. And always get the updates in the Software Center. The Desktop Icons are also gone.
