Using Deja-Dup to back up to a network share from a Lubuntu 18.04.1 laptop.
Deja-Dup properly asks for credentials for the share, and offers the option to save the password by ticking a box. Which I do. The backup goes as desired, no problem.
The next time I do a backup, I have to input the credentials again. Ticking the "save password" box does not, in fact, save the password.
Could this be a keyring problem? I've had keyring issues with Lubuntu before.
