Hello, In commit ffb1652c4ada9595dc74773d3ccd409ec10280a1 Ihor removed the "jump" submodule located at "testing/jump". However, they did not remove the ".gitmodules" file that specifies the git module. This is causing strange errors for me when using guix to build org-mode in its container like environments. Due to the complexity of the software involved, it would be difficult to give a more precise error then what I've described.
Please consider removing the file. Thanks, Morgan
