In a workstation with Ubuntu 18.04 using EUFI, new entries (related to devuan and Debian) were inserted before the Ubuntu entry. The workstation does not have those OSes so I am not sure why they did showed. I am assuming they were inserted by the faulty grub2 update.
Anyway, I edited (using the BIOS) those entries so Ubuntu boot is listed first and it fixed the problem in the workstation.
Now it boots normally. I updated packages and still is booting.
