The Jupyter extension for VS Code wants to update but fails to do so. I am not sure which version of the extension I had installed before I uninstalled it and then tried to reinstall (read below). I don’t have this issue with any other extension, which means I can install other extensions from the GUI within VSCodium without issues. I am using VSCodium (version 1.88.1, snap) on Ubuntu 22.04 LTS.

Jupyter Extension wants to update

When I click the “Update to v…” button, I get the following error:

[error] Invalid comment length. Expected: 63. Found: 0. Are there extra bytes at the end of the file? Or is the end of central dir signature `PK☺☻` in the comment?: Extract: Invalid comment length. Expected: 63. Found: 0. Are there extra bytes at the end of the file? Or is the end of central dir signature `PK☺☻` in the comment?

I tried uninstalling the extension and reinstalling.

1. from the VSCodium GUI (whereas the extension version would be 2024.5.0)
2. from terminal by downloading the .vsix file from the marketplace first and then running codium --install-extension ms-toolsai.jupyter-2024.5.0.vsix and after failing i tried codium --install-extension ms-toolsai.jupyter-2024.3.1.vsix

Both methods returned the same error message. I then tried to download the 2023.9.100 version and install this one and it worked.

Comparing the .vsix files, I noticed that the 2023.9.100 version was an archive while the two newer versions were just text files.

2023.9.100 vsix-file is an archive

2024.5.0 and 2024.3.1 vsix-files are text files with weird symbols
