[Bug 1767761] Re: Could not delete variable: Interrupted system call (package shim-signed 1.34.9+13-0ubuntu2 failed to install/upgrade: installed shim-signed package post-installation script subprocess returned error exit status 1)

Hi Gustavo, thanks for following up.  If you are affected by
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1734147 please look
at the information there about using a custom kernel to recover your
firmware's writable state.

For the record, you mention having problems after installing Ubuntu
17.04, but this bug only affected systems which were running Ubuntu
17.10.  But the symptoms you're describing certainly sound like this
bug, so I would guess that you just have mentioned the wrong version
number.
