Cant't start electrum wallet any more :(

Hey guys,

lately i wanted to start my electrum bitcoin-wallet installed
electrum/green,now 3.1.1-1 all [installiert]
although the actual version is 3.1.2 …
but the output was:
xtops@t420:~$ electrum
Error: Could not import PyQt5 on Linux systems, you may try ‘sudo apt-get install python3- pyqt5’
when trying install python3-pyqt5 i get:
Die folgenden Pakete haben unerfüllte Abhängigkeiten:
python3-pyqt5 : Hängt ab von: qtbase-abi-5-9-0 ist aber nicht installierbar
E: Probleme können nicht korrigiert werden, Sie haben zurückgehaltene defekte Pakete.
i hope you understand the german output, it just means a dependency of qtbase-abi-5-9-0 , which is not installable!

what can i do? Or anyone knows when it will be fixed??

Thanks in advance
