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

[Luca Bertoncello]

Hi Edgar,

no Problem!
As you see, the keys are here:

root@mail ~ # gpg --list-secret-keys --homedir /opt/backup/keys/backup/
/opt/backup/keys/backup//secring.gpg
------------------------------------
sec   2048R/5E0FF919 2021-07-19
uid                  BACKUP <it@queo-group.com>
ssb   2048R/B8D4D817 2021-07-19

root@mail ~ # gpg --list-secret-keys --homedir /opt/backup/keys/restore/
gpg: checking the trustdb
gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model
gpg: depth: 0  valid:   2  signed:   0  trust: 0-, 0q, 0n, 0m, 0f, 2u
/opt/backup/keys/restore//secring.gpg
-------------------------------------
sec   2048R/583232D4 2021-07-19
uid                  RESTORE <it@queo-group.com>
ssb   2048R/640278DF 2021-07-19

Thanks
Luca

ok,

let's continue on list for the archives. nothing new or specific in the log. 
you are running the backup as root.

please run a root shell and check that 'gpg --list-secret-keys' lists the 
missing key. supposedly it's called "RESTORE <it@queo-group.com>". it seems to 
be missing in the root keychain!
