Hello, a few days ago I incientially found a way to resolve the issue on my ubuntu 16.04 machine. For me the issue appeared as a popup every time the lightdm login screen was loaded.
As I added another user I moved the certificate folder which contains the certificates from my encrypted home folder the a subfolder of root ie. /mycertsfolder/certificatefile.cer, the issue was gone. The reason I did this was the encrypted home folder was not readable by the new user that was added. Hopefully this helps best regards Kitsab -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1339607 Title: "Unencrypted private keys are insecure" message is vague and unhelpful To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/1339607/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
