git submodule update --depth 1: reference is not a tree

[listcrawler@…]

Shallow clone of super and sub projects does not work for release 1.65.1. Recreate with:

git clone --depth 1 --branch boost-1.65.1 https://github.com/boostorg/boost.git boost
git -C boost submodule init libs/config
git -C boost submodule update --depth 1

yields:

fatal: reference is not a tree: 2c5de25f2d1aea9316129027e6617649a0e09e59

Update without depth 1 works fine:

git -C boost submodule update

Other libraries (context, core, fiber, system, tools/build) have the same problem.

Not sure if this is intended to be supported - but if so it's an issue with the git super-project - please file an issue on github against that.
