[Bug 1870955] Re: MokManager - Only DER encoded certificate (*.cer/der/crt) is supported

[Steve Langasek]

What were the steps you took to try to manually add the certificate?

The /var/lib/shim-signed/mok/MOK.der file that we populate is certainly
a DER-encoded certificate, and users have been successfully registering
these certificates through MokManager.

What version of the shim-signed package do you have installed?

Title:
  MokManager - Only DER encoded certificate (*.cer/der/crt) is supported

Status in shim-signed package in Ubuntu:
  Incomplete

Bug description:
  Installation of VirtualBox requires signing kernel modules.
  During installation a certificate is generated. It should be automatically added during system reboot. However, this is not happening.

  Manual attempt to add a certificate:
  After selecting the generated certificate the following error occurs:
  "Only DER encoded certificate (*.cer/der/crt) is supported".
  I managed to establish that it was MokManager's fault. It does not allow adding ANY certificate.
