[solved] Netrunner 19 Desktop Debian Thunderbird 45.8.03

How I can get rid of Thunderbird 45.8.03 and install the latest version 60.xx without dependency issues inclusive language package german 60.xx? Thank you.

The easiest way for now is to disable the plasmazilla component from netrunner-backports.list in /etc/apt/sources.list.d/

Thank you. All right. I am using KMail and so I solve this issue with uninstalling Thunderbird.
