SBC: Can't downgrade from 3.4.5-1

gnydick

When I try to downgrade reprapfirmware from 3.4.5-1 to 3.4.4-1, every attempt fails. I have no choice but to downgrade since the 3.4.5-1 update killed all of my toolboards.

apt just can't do it. synaptic will force you to downgrade through every version and eventually uninstall everything.

I suspect the dependency tree isn't setup properly.

I figured out I could force the installation by downloading the packages directly and installing them by hand instead of letting the package manager handle it. Tools have reappeared!

Did you used --allow-downgrades argument to apt to allow downgrading packages ?

@gnydick I have just tried using the rrf_upgrade script I made for TeamGloomy SBC builds which can be found here : https://github.com/TeamGloomy/rrf_stm32_sbc/blob/master/armbian/userpatches/overlay/rrf_upgrade.sh
And documentation here : https://teamgloomy.github.io/armbian_upgrade.html#upgrading-dsf

rrf_upgrade 3.4.4 downgraded the Duet packages from 3.4.5 to 3.4.4 without issue.

@Falcounet the way it resolved the downward dependences, it would have downgraded the firmware all the way from 3.4.5->3.4.4->3.4.3---> uninstalled. Very strange.
