Having a corrupt git repo is scary.

For the last few weeks I’ve had this blog’s git repo getting randomly corrupted.

Summary: There is a fix on the Windows Dev Insider Build - 21292. I’m currently on stable build of 19042.804

Error: object file is empty

I’ve had this blog’s git repo getting corrupted with errors like:

error: object file .git/objects/79/cbddeb3c2e2e6cb41f301bdf1e10c0508066e3 is empty
error: object file .git/objects/79/cbddeb3c2e2e6cb41f301bdf1e10c0508066e3 is empty
fatal: loose object 79cbddeb3c2e2e6cb41f301bdf1e10c0508066e3 (stored in .git/objects/79/cbddeb3c2e2e6cb41f301bdf1e10c0508066e3) is corrupt

These are sitting on a fully patched Win10 machine (29th Jan 2021) runing WSL2 fully patched. The files are sitting WSL side ie in /home/dave/

Git Version

I had version 2.17.1

Lokking at git-scm I can see the latest is 2.30.0 so lets see if this helps

sudo add-apt-repository ppa:git-core/ppa
sudo apt update
sudo apt install git

okay now I’m at 2.30.0

This didn’t work
