apt upgrade fails on /boot being mounted ro. #183

Closed gmos closed 3 years ago

gmos commented 4 years ago

If apt upgrade wants to upgrade a bootloader or kernel on /boot it fails because /boot is normally mounted ro. It is easily fixable by remounting /boot rw and then do an apt --fix-broken install, but it should not fail during the upgrade.apt upgrade This happened last with upgrade from kernel 1.20200601-1 to kernel 1.20200717-1. But also with a previous upgrade.

Some info: PRETTY_NAME="Raspbian GNU/Linux 10 (buster)" NAME="Raspbian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)"

This is on a Pi Zero W.

/boot is normally mounted ro.

It certainly shouldn't be. I don't know what the expected behaviour would be if you're trying to write files to a read only file system, but failing seems like the right thing to do.

Indeed. So the bug is in apt or in the scripting of the kernel/bootloader upgrade. Apt/script should remount /boot in rw mode before the actual upgrade starts. As it did in the past.

By default, /boot is not mounted read only though. If the user has decided to make it read only for some reason, it's not up to a package maintainer to mess with that.

Then that may be the problem. I’m pretty sure I have started this card with a vanilla install of Raspbian Buster Lite a month or two ago. And that I never have changed the mounting mode of the boot partition myself. But I’ll have to set-up an SD card for a new Pi anyway. So I’ll get the latest official Buster Lite image an report back here how /boot ends up after a fresh install.
