Re: [Duplicity-talk] Serious problem with duplicity - secret key not available

[Luca Bertoncello]

Hi Edgar,

I downloaded and installed Duplicity 0.7.19.
Unfortunately I always get the same problem... ☹

Any other idea?

Thanks
Luca

hey Luca,

duplicity 07.06 is very very old and not even the latest in the now 
unmaintained branch. please install either latest duplicity 0.8.20 or 0.7.19 
manually after removing the old version from your distribution.
http://duplicity.nongnu.org/ (section Download)

there are ppa, snap and pip3 installations available. if that does not suffice 
or is impossible, there is a 'INSTALL MULTIPLE VERSIONS' mini-howto on 
https://duply.net/Documentation (never tried with 0.8.x though, the executable 
patching may need some modification there).

please come back if the error persists with one of the above versions and we'll 
try to resolve it for good.

good luck and healthy regards.. ede/duply.net
