MX 19 KDE update failure [Solved]

[uncle mark]

My old trusty MX 19 KDE is throwing up an error while trying to update:

Code: Select all

full upgrade complete (or was canceled)

Suggestions?

remove linux-firmware and install mx-debian-firmware. looks like debian has introduced a conflict. the microcodes didn't used to be part of these things.

Code: Select all

sudo apt install mx-debian-firmware

linux-firmware is an alternate package.

Linux-firmware is an Ubuntu package that I ported over when Debian didn't have anybody updating their many firmware packages for an entire year.
Ubuntu just put all their firmware and microcode files into one big package. Since Debian starting updating their packages again, it has been deprecated.
