I am not even sure which “auto-fill” breaks it (LastPass or Chrome, on my case), but I really struggled to restore a backup because of it last month. I just found out (thanks quinting and Fiermont !) that it also breaks the creation of backups and finally solved the dreaded 2 warnings at the end of some of mine!
I’m using Google Drive, but the solution is the same is the one proposed by Fiermont: Nov '19. You just edit the destination URL, on second step “Destination” of the GUI, removing everything after the authid=[key] (i.e., after the huge string after authid=, starting with the &auth-username=).
Every successful backup, for quite some time until today, would end with 2 warnings:
2020-08-27 15:30:10 -03 - [Warning-Duplicati.Library.Main.Controller-UnsupportedOption]: The supplied option --auth-username is not supported and will be ignored
2020-08-27 15:30:10 -03 - [Warning-Duplicati.Library.Main.Controller-UnsupportedOption]: The supplied option --auth-password is not supported and will be ignored
And now I was finally able to solve it, without the need to recreate the jobs (and lose all blocks already at the destination).
Thank you so much for reasserting what quinting and Fiermont has explained. I actually shifted my duplicati backup from icedrive to google drive. These two errors were pop up when I run the backup to google drive.
I was looking for the auth password to remove as explained but was difficult finding where in the destination screen. I was checking in the advanced option three dots and was overlooking on the top three dots.
So i finally found here in the screenshot Screenshot by Lightshot. First i copied the URL which came after pressing the 3 dots and then importing but removing &user… password until end. Screenshot by Lightshot
The error goes off. Thank you everyone for the help.
This was the solution for me as well, although Firefox password manager. Once removed from there, the backup again worked well. THANKS, I never would have figured that out!
