Hello Bilal,
Summary of Warnings:
Could not update cactuswave. Could not stash local changes. Error message was 'You do not have the initial commit yet '. Could not update einsteinanalysis. Could not stash local changes. Error message was 'You do not have the initial commit yet '. Could not update lean_public. Could not stash local changes. Error message was 'You do not have the initial commit yet '.
These three repositories (repos/cactuswave repos/einsteinanalysis repos/lean_public) were left in an invalid state due to previous failures it seems.
You can manually delete them using
rm -rf repos/cactuswave repos/einsteinanalysis repos/lean_public
and after that GetComponents should be able to download fresh, error free copies.
Alternatively you can also remove the full failed Cactus checkout ie:
rm -rf Cactus
and try once more from scratch using the --no-parallel option.
Yours, Roland
