The sha exists in mono/linker, so may be an issue in Darc or LibGit2Sharp.

the issue seems to occur when handling the external/cecil submodule

It looks like this is using /source-build/.git/modules/src/linker.git/modules/external/cecil, which is at an older version:

commit a6c8f5e1070d25c38cbfaa415d6f6853e5236687 (HEAD, origin/master, master)
Merge: b6000d6 fcf446f
Author: Marek Safar <[email protected]>
Date:   Thu May 23 13:36:10 2019 +0200

    Merge remote-tracking branch 'upstream/master'

and doesn't have the commit being checked out:

$ git show cb6c1ca9aaef869841bfc3e2e7407b81b979b875
fatal: bad object cb6c1ca9aaef869841bfc3e2e7407b81b979b875

I removed my source-build folder, and started from a fresh clone, and now it works.

@crummel to follow up with darc to either eliminate or upgrade libgit2sharp

@crummel I'll close this. Was there some way to update the modules without doing a fresh clone?
