[Duplicity-talk] LookupError: unknown encoding: unicode-escape

[Jan Hartmann]

Hello,

On a long-running Ubuntu server (LSB 14.04.6 LSB) backups have been made 
with Duplicity 0.6.23 since July 2016. All packages have been regularly 
upgraded to their latest versions, but nothing else has been changed. 
Even so, from about May 2020, duplicity crashes with the error below.  
Can anything be done about this?

Jan Hartmann
