Spyder not working with Ubuntu 22.04 after installation with either aptitude or apt-get

[Fausto A. A. Barbuto]

Hi,

I love Spyder, but it has become increasingly problematic to install.

I've had problems with Spyder since about version 4.0 or maybe a bit

earlier than that, but now things seem to have reached a point of no 

return.

I recently upgraded my Ubuntu installation from 20.04 to 22.04 and

noticed that Spyder stopped working. I then uninstalled the version

I had with apt-get and reinstalled it in the hopes that it would

then work. After all, apt-get is the "official" way of installing 

Ubuntu packages, right? It should work. Well, it didn't and produced 

the following output:

$ spyder

  scaled(self, QSize, aspectRatioMode: Qt.AspectRatioMode = Qt.IgnoreAspectRatio, transformMode: Qt.TransformationMode = Qt.FastTransformation): argument 1 has unexpected type 'float'

I'm lost. Since Spyder is in the repository as an "official" package

it should be installed. But neither apt-get nor aptitude worked.

It is strongly recommended that Spyder should be installed under

Anaconda, but I don't see myself installing ~1 GB of useless clutter

just and only to get Spyder working. I want Spyder as it was before 

the upgrade. How could I do this?

Thanks a lot for any help.

Hi Fausto,

Sorry for the inconvenience, but there is not much we can do. For more info about the Spyder distribution on Linux you can check this issue: https://github.com/spyder-ide/spyder/issues/17422

Basically, the Spyder team only releases the package through PyPI, conda and by building standalone installer for Windows and MacOS currently.

Let us know if the info in the issue linked above helps!

Best regards,

Daniel

I don't think the apt package for spyder works...

You can install Spyder using Miniconda instead of Anaconda... Ensure to intialise Miniconda it in the last steps of installation. 

Miniconda is a barebones version of Anaconda giving an empty base environment with the conda package manager.

 

To get the latest version of Spyder, it is recommended to install it in a new conda environment using the commands:

```

conda create -n spyder-cf 

conda activate spyder-cf 

conda install -c conda-forge spyder

conda install -c conda-forge cython seaborn sympy openpyxl xlrd xlsxwriter lxml sqlalchemy

```

The last command gives the optional dependencies for spyder such as numpy, pandas, matplotlib (all dependencies of seaborn) and file format converters (used by pandas).

To launch you will need to activate your conda environment using:

```

conda activate spyder-cf 

spyder

```

I cover the installation on Ubuntu 22.04 LTS here:

Hi Philip,

Hi Daniel,

More recently, I installed VS Code for the sake of a Spyder's replacement and so far I'm getting along well with it.

I didn't know there was VS Code (a Microsoft product) for Linux, but there is. Clean install, good looks, lots of

options (way more than I actually need). I still miss a few Spyder features, but c'est la vie.
