Duet Pi Regression - How?

and purging duetsd will clear out the most of /opt/dsf/sd folder ~~configs, macros, gcode, everything.~~

Why is that 95%? Or what is the 5% edge case?

oh, and there is something weird with the reprapfirmeware n.n.n.n-1 and n.n.n.n-999 dependenices for otherwise identical versions. so i ignore the 999 in the rexeg

Agreed. I'm now on the warpath to avoid 'apt purge'.

'apt remove' only removes things in the package manifest, and deletes empty directories. If non empty, it will leave them. I believe the one time I regressed (by a manual method) that everything stayed intact, EXCEPT config.g had been overlaid with the empty-ish distribution copy. All other files, like tfree and tpost and so forth, and macros, they were all intact.

Me too.

With regard to "how to recurse" without depending on the exact structure of the package, this seems to work, then parse the "depends" line:

apt show duetsoftwareframework=1.2.3.0
Package: duetsoftwareframework

missing duetruntime which is why i turne to recusion that ultimately failed if left run to to all the leaf nodes.

Danal

Hmmm... I wonder how it gets installed? With no dependency?

duetcontrolserver has it as a dependency iirc (thus the recursion)

Danal

Ah, light bulb just came on. Thank you.

Danal

And, by the way, autopurge (which I am NOT going to use) actually does not purge the recursive stuff after a

sudo apt install duetsoftwareframework=1.2.3.0 duetcontrolserver=1.2.3.0 duetruntime=1.2.3.0 duetsd=1.0.5 duettools=1.2.3.0 duetwebserver=1.2.1.0 duetwebcontrol=2.0.4-1 reprapfirmware=1.2.3.0-1

style install, and an apt remove duetsoftwareframework.

So.... it would not have worked anyway.

Just switch to RPM

was wondering if aptitude* would be better suited, but decided to brush up on regex instead

*) not better than RPM..

How about //STEP1 EXEC PGM=SMPE? It handled prereqs, coreqs, and even postreqs flawlessly. Why, I've heard you could build and entire OS with it!

apt remove duet* reprapfirmware is about the same length and oddly more specific. would work with remove and purge for that matter.

Yah, I thought about the nicely structured names. As you said though, if the package changes...

then it has a greater chance of catching it as duetruntime still doesn't depend on duetsoftwareframework.

and if apt remove duetcontrolserver duetruntime duetsd duetsoftwareframework duettools duetwebcontrol duetwebserver reprapfirmware is the alternative then it needs to be updated anyways.

to be honest I have more faith in a * than apt and dependencies defined for the packages should autoremove fail.

Danal

OK, here is a "first draft" that works. Comments welcome:

./DuetRegress.sh 2.1.0
Currently Installed duetsoftwareframework=
Command line argument is requesting duetsoftwareframework=2.1.0
Which has associated reprapfirmware of 2.1.0-1 also known as 3.01-RC9

***********************************************************************************
* Note: The next step will run for a while; the script is (probably) not hung.    *
***********************************************************************************

To regress to DSF version 2.1.0 which is RRF version 3.01-RC9:
1) Backup your files via:
  mkdir ~/duetback
  cp -r /opt/dsf/sd/* ~/duetback
or similar. Verify that the backup worked: 'ls ~/duetback' should show directories: 'filaments firmware gcodes macros sys' or similar.

2) Run this command: (it is long, be sure you get it all on one line)
  sudo apt -y  --allow-downgrades install duetsoftwareframework=2.1.0 duetcontrolserver=2.1.0 duetruntime=2.1.0 duetsd=1.0.6 duettools=2.1.0 duetwebcontrol=2.1.4 duetwebserver=2.1.0 reprapfirmware=2.1.0-1

3) Verify system is running properly, web interface opens, etc

4) If Pi runs, but won't connect to Duet Board, bossa the board
   with the file found at /opt/dsf/sd/sys/Duet3Firmware_MB6HC.bin
   Instructions here:
   https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Updating_Duet_3_main_board_firmware

5) Check files like config.g, macros, etc, and restore as required.

There are no name or other recursion dependencies in the script. Also, I took out the "apt remove" command, I don't believe it is required, apt will just overlay things.

i opted for splitting the lines so it can be easy to read and copy, or if piped/backticked its not.

i'd also reconsider the -y bit gives apt a chance to complain if it feels the need.

pi@raspberrypi:~ $ bash rrfdep.sh 3.01-RC9
sudo apt install \
  duetcontrolserver=2.1.0 \
  duetsd=1.0.6 \
  duettools=2.1.0 \
  duetwebserver=2.1.0 \
  duetwebcontrol=2.1.4 \
  reprapfirmware=2.1.0-1 \
  duetsoftwareframework=2.1.0
pi@raspberrypi:~ $

don't think i'll put up the version that resolves it from the reprap firmware version, smells like lots of unnecessary load on servers just to save people looking up a table

Danal

Excellent idea on the lines! I will do that. In fact, I was a bit concerned about line length... not only that, but I'm flattening a 'list' now, all I have to do is not do that.

I go back and forth on the -y. Given that this is intended to be used by people who literally can't even answer the initial "Do you want me to do what you asked? [Y/n]" prompt... well... I'm inclined to leave it in.

re: servers, yeah, this one is entirely local. In fact, it ought to insist on a recent (whatever that means) sudo apt update.
