[Duplicity-talk] duply duplicity keyfile not found on centos 8

[Probst, Martin [IVZ]]

Hello list,

on Centos 7, my duply setup with encryption works fine.

Now Centos 8 it looks like there is an problem with reading the gpg keys.

 in the profile folder. If not you can put it there and duply will autoimport 
it on the next run. Alternatively import it manually as the user you plan to 
run duply with. Maybe you have not created a gpg key yet (e.g. gpg --gen-key)? 
Don't forget the used _password_ as you will need it. When done enter the 8 
digit id & the password in the profile conf file. The key id can be found doing 
a 'gpg --list-keys'. In the example output below the key id would be FFFFFFFF 
for the public key. pub 1024D/FFFFFFFF 2007-12-17 uid duplicity sub

Centos 8 comes with duplicity version 0.8.16. I installed 0.8.17 too, same 
message.


The different between Centos 7 and Centos 8 is the lenght of the key id. 8 
chars Centos 7 and 40 chars on Centos 8.It seems like duply is not using th 40 
char key id's

greeting
