Failed to parse .SRCINFO

Getting this on several packages:

% aura -A ros-noetic-desktop

aura :: There were multiple errors during dependency resolution.

There are occasionally git clone failures when many are attempted at the same time. I haven't yet implemented a retry policy but plan to for such cases. Usually if you try again it works. If you notice that a directory (say, python3-xcgf) has appeared in ~/.cache/aura/packages/ but it is empty, then it will need to be deleted manually. Note that aura check can also detect such failed clones.

Any thoughts?

I don't have any empty directories in ~/.cache/aura/packages.

% pwd
/home/user/.cache/aura/packages
% tree | wc -l
431
% tree --prune | wc -l
431

aura check output: https://paste.xinu.at/UH1M

edit: I no longer have the errors with 4.0.4, but the diagnostics should be improved. "Failed to parse .SRCINFO" could mean any number of issues (missing file, unexpected fields, wrong indentation, etc)

I have noticed two things:

1. There is currently no retry policy for lookups.
2. For packages with large, AUR-based dependency graphs that highly inter-depend, it may be that a lookup failed on one branch but succeeded on another, which generates spurious error messages.
