[Bug 1893495] Re: package shim-signed 1.37~18.04.6+15+1533136590.3beb971-0ubuntu1 failed to install/upgrade: installed shim-signed package post-installation script subprocess returned error exit status 1

[Steve Langasek]

The error in your log is:

sh: printf: I/O error

It is unclear to me how this error occurred.  It appears that you were
attempting an upgrade from xenial to bionic, but not using the release
upgrader, and that stdout/stdin have somehow been disconnected from any
tty, resulting in read/write failures for the maintainer scripts.  I am
not sure this is a bug that can be fixed in shim-signed.
