[SRU] pronterface does not start in jammy

Status changed to 'Confirmed' because the bug affects multiple users.

I'm having the same issue on a clean install of Xubuntu Jammy 22.04:

It happend on upgraded ubuntu 22.04 from 20.04. On Ubunti 20.04 Pronterface worked very fine.

Hello
do we have any news about this very annoying problem? Or a temporary solution?
Thanks a lot

Temporary workaround: Check out original software and run it directly from this directory:

Get software (git has to be installed)

$> git clone https://github.com/kliment/Printrun

Change into new fetched directory:

$> cd Printrun

Run pronterface:

$> ./pronterface.py

Big thank you and little hello for you Dennis.
I managed to reuse Pronterface with Ubuntu 22.04 after some difficulty adding "wxpython" solved with:
https://www.pixelstech.net/article/1599647177-Problem-and-Solution-for-Installing-wxPython-on-Ubuntu-20-04

On the other hand, I don't know how to integrate slic3r yet. But I will search.

Have a good evening.

I have the same issue on Linux Mint 21.

me too:
$ pronterface ...
 File "/usr/lib/python3/dist-packages/printrun/gviz.py", line 197, in __init__
    self.mainpen = wx.Pen(wx.Colour(0, 0, 0), penwidth)
TypeError: Pen(): arguments did not match any overloaded call:
  overload 1: too many arguments
  overload 2: argument 2 has unexpected type 'float'
  overload 3: argument 1 has unexpected type 'Colour'

Same pronterface will not start up

I hope there is a solution ..i already tried the workaround works but can not trust if it works properly

Dear Ubuntu team,

This is an annoying issue that should be fixed to allow a proper user experience on LTS release such as Jammy. The problem happens because of Python 3.10+. To solve this bug, please consider:

 a) backporting the current stable (Lunar Lobster) printrun version 2.0.0~rc8-2build1 (which includes the fix for working with Python 3.10+)

 b) cherry-picking the patch to solve the issue [1]

PS/Disclaimer: I am the maintainer of printrun in Debian

[1]: https://salsa.debian.org/3dprinting-team/printrun/-/blob/608965bebd407b94ef99b648cc22f95f4211b1d5/debian/patches/0003-Fix-a-TypeError-on-Python-3.10.patch

Regards,
Rock

This bug is exposed by changing from python 3.9 to 3.10. I reported this bug (in a Fedora release) to printrun two years ago, and it was fixed almost immediately.

The link to the printrun-reported bug is below.

https://github.com/kliment/Printrun/issues/1225

This comment brings a similar comment in duplicate https://bugs.launchpad.net/bugs/2045487 to this original bug report.

The current printrun release of Pronterface does not work properly with wxpython 4.0.x; it requires at least 4.1.x. Generating custom buttons does not work because it uses GetLuminance, which was only introduced in 4.1.0.

Updating wxpython could affect other apps.

Trying to get the current release of Pronterface to work.

This issue I found using wxpython 4.0.7 (as supplied by Ubuntu) is that the pronterface button-handling code uses the wx.Colour GetLuminance attribute, which is supplied only in wxpython 4.1.0 and later.

I tried user-installing later versions of wxpython, but 4.1.0 wouldn't compile, and 4.1.1, 4.2.0 and 4.2.1 all resulted in pronterface displaying a black rectangle in place of the build surface.

So for the moment I have modified pronterface.py (in the package, not the top level).

if b.GetBackgroundColour().GetLuminance() < 0.5:
    b.SetForegroundColour("#ffffff")

is changed to:

try:
    if b.GetBackgroundColour().GetLuminance() < 0.5:
        b.SetForegroundColour("#ffffff")
except AttributeError:
    cxx = b.GetBackgroundColour().GetRGB ()
    lxx = 0.299 * (cxx & 255) + 0.587 * ((cxx >> 8) & 255) + 0.114 * (cxx >> 16)
    if lxx < 127.5:
        b.SetForegroundColour("#ffffff")

For the moment, this is the only way I can get Pronterface to work. This is not a distributable fix; we need to work out why later versions of wxpython don't work properly.

I can reproduce the issue in Jammy and have also confirmed that it works on Lunar. So, only Jammy is affected.

debdiff for Jammy attached.

Hello Dennis, or anyone else affected,

Accepted printrun into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/printrun/2.0.0~rc7-1ubuntu0.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

This fix works fine so far for me. Thank you.

apt list pronterface gave:
pronterface/jammy-proposed,jammy-proposed,now 2.0.0~rc7-1ubuntu0.1 all [installed,automatic]

I can confirm that the pronterface package in jammy-proposed has fixed the bug for me.

Test done:
1. Install pronterface on a jammy installation.
2. execute pronterface.
   - It fails to run.
3. Add jammy-proposed to apt sources
4. Update pronterface from jammy-proposed.
5. execute pronterface again.
   - pronterface gui is displayed.

Test result: the errors with pronterface has been fixed and it can be executed again

Package tested:

$ dpkg -l | grep pronterface
ii pronterface 2.0.0~rc7-1ubuntu0.1 all Graphical 3D printer host

Just to fill in on what testing I have done (see 2024-01-08 comment above).

Started pronterface.
Connected to printer.
Loaded file to print.
Set bed temperature.
Set extruder temperature.
Confirmed that custom button displayed and worked.
Printed the file.

FYI no checksum or line number errors displayed while printing file (unlike when using a version of printrun that I hacked to (sort of) work).

Disconnected from printer.

This bug was fixed in the package printrun - 2.0.0~rc7-1ubuntu0.1

---------------
printrun (2.0.0~rc7-1ubuntu0.1) jammy; urgency=medium

  * Apply upstream patch to fix TypeError on Python 3.10+. (LP: #1975947)
