From time to time our laptops receive firmware updates, by using the Linux Vendor Firmware Service (short: fwupd). This worked fine for a long time, until it didn’t. One day I was facing the following error message:

root@laptop:/root# fwupdmgr update

During the first few occasions I basically ignored the error message, and attributed it to a glitch in a software package. Maybe a later update will fix this.

But this never happened, so I looked into the issue.

Ubuntu split the 1.6.x version of fwupd into separate packages, and does not install the packages fwupd-signed and fwupd-unsigned to deal with EFI binaries.

1
apt-get install -y fwupd-signed fwupd-unsigned

Now everything is working again:

root@laptop:/root# fwupdmgr update

║                                                                              ║

Voila! Also updated the playbook which installs the laptops, to include the two new packages.
