Public bug reported: Hello!
Besides issue with shim itself described in Bug 1849863 I noticed that there is also issue with shim-signed package installation script. Attempt to install shim-signed on Lenovo Yoga C630 WOS cause following errors and left shim-signed package in unconfigured state, which will cause more issues later on (for instance update-manager will always try configure shim-signed on every upgrade).
