Cura does not start

ocsen · 7 2024 09:45

On my system Ultimaker Cura fail to start; the following is the output of launching it from terminal:

$ cura
Traceback (most recent call last):
  File "/usr/bin/cura", line 24, in <module>
    from UM.Platform import Platform
ModuleNotFoundError: No module named 'UM'

I’ve found a similar issue here , where the user finally realizes what was wrong:
“it was using anaconda, i am activating in my profile, i deactivated the env and cura runs from bash just fine.”

I’ve checked by pamac and anaconda is not installed on my system; bash it is, while no one else of other bash related packages is installed.

The outputs of the other checks which were required to that arch user are:

$ python -c "import UM; print (UM.__file__)"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'UM'

$ pacman -Qkk uranium
uranium: 424 total files, 0 altered files

$ which python
/usr/bin/python

How can that be fixed?
I’d like not to uninstall Cura, if possible, so as to keep its configuration.

Looks like an AUR package. You need to rebuild after the underlying Python version changed.

Uninstalling a package does not touch any files in $HOME or other configuration files.

ocsen · 7 2024 09:52

so I should unistall and reinstall?

Nachlese · 7 2024 10:05

No need to uninstall.

But it depends on which package you chose - there is a cura-bin and a cura which is built
but the latter is flagged as out of date:

AUR (en) - cura

When you use another - uninstall the one you have.
But this should be taken care of via the dependency declared in the PKGBUILD.

ocsen · 7 2024 10:32

The installed package is cura 4.13.1-1, cura-bin is not installed

dmt · 7 2024 10:55

Have you rebuilt it yet?

yay -S cura

# or 
pamac build cura

Nachlese · 7 2024 11:24

It will likely fail to build - it’s flagged out of date (link).
@ocsen
The cura-bin is a higher version and does not need to be built.
win - win ?

cave:
I don’t even know what cura is - I was just going by the name.

Fair enough…I always avoid bins, you never know how they’re compiled.

It’s a slicer for 3d printing.

linux-aarhus · 7 2024 12:45

The error speaks for itself

Rebuild cura - it is a custom package …

If the configuration lives in your home - it is going nowhere

ocsen · 7 2024 13:36

So I tried to rebuild cura via pamac, but it stopped on “Entering fakeroot environment” - it’s blocked there, should I exit?

It could be that you are on stable branch - AUR often requires unstable branch to build correctly.

[root tip] [How To] Update Manjaro the smart way

I think you need to take a walk around the maintainer at AUR.

Cura has a lot of AUR dependencies which you may need to resolve manually.

I get a failed dependency arcus - could be a package got renamed - because I can only find package named libarcus.

Even so - you will only get it to build with some manual intervention.

As I see it you need to resolve these manually

==> Missing dependencies:
  -> python-pyqt5
  -> python-scipy
  -> python-numpy
  -> uranium
  -> curaengine
  -> libsavitar
  -> python-pynest2d
  -> python-keyring
  -> python-trimesh
  -> cura-resources-materials

@ocsen
You will get a cascading build failure using the PKGBUILD because

it depends on the custom uranium script
which if lagged out-of-date on 2023-05-11
which in turn depends on arcus
which in turn does not exist

 $ pamac info arcus
Error: target not found: arcus

Teo · 7 2024 13:51

You need to install base-devel FIRST.

Nachlese · 7 2024 13:57

Use another AUR helper (yay, for example) - or use what is recommended:
makepkg

install base-devel - it wasn’t installed, now it may be
it is a prerequisite for building AUR packages

as already said:
this package is marked as “out of date” - so, problems are to be expected, even if you where using ARCH - which you are not

Wait until the package is fixed at least for ARCH -
even then no guarantee that it will then build with Manjaro stable

If you can’t fix it … don’t use it.
Perhaps there is a flatpak or appimage - don’t know.

But then you can just as well use the -bin version (in my opinion).

you are trying to build 5.3.0-1
the binary package does not require compilation
and is version 5.8.0-1

ocsen · 7 2024 14:01

yes, it has just been installed after “pamac build cura”, it is on the first rows

linux-aarhus · 7 2024 14:08

Forget it - you cannot make it build - see my comment above.

If you hunt down all the prerequites

then you may succeed
but it is manual labour
good luck

ocsen · 7 2024 14:13

Yes, I will look for an easier way.
Thank you all for your help

Nachlese · 7 2024 14:20

exactly right

I don’t know the software - and thus of no reason to keep maintaining a lower version that what is otherwise available.

oh - you edited your post and now mine looks odd - oh well
