Hello Konrad,
I can use the other machine to pull everything of course, but perhaps there's yet some fix that I could try?
The simplest fix is most likely to change einsteintoolkit.th in this manner:
* replace all TYPE=svn by TYPE=git * remove all /branches/$ET_RELEASE and /trunk (whichever one is present)
Run GetComponents with the edited thorn list.
This will get the full git checkout so is a bit larger, but avoids svn issues with GitHub and Ubuntu. You may be seeing an instance of this:
https://bitbucket.org/einsteintoolkit/tickets/issues/2396/potential-issue-wi...
though there at least some output was produced.
Yours, Roland
