Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue. What did you do before the bug happened? (Steps to reproduce your issue) (I tried to come up with dummy repos with a similar relationship but failed to reproduce the issue there, and --filter doesn't work for local repos, so I gave up and I'm just using the repos where the issue occured instead) This does a treeless clone of an outdated fork, then adds the upstream and fetches from it. rm -Rf MINGW-packages git clone --filter=tree:0 https://github.com/lazka/MINGW-packages cd MINGW-packages git remote add upstream https://github.com/msys2/MINGW-packages git fetch upstream What did you expect to happen? (Expected behavior) fetching in the treeless clone works as with a non-treeless clone What happened instead? (Actual behavior) fatal: bad revision 'e346057a67cffe54493cf87e24498229b8a370cc' error: https://github.com/lazka/MINGW-packages did not send all necessary objects fatal: could not fetch e346057a67cffe54493cf87e24498229b8a370cc from promisor remote fatal: fetch-pack: invalid index-pack output What's different between what you expected and what actually happened? The treeless clone does not work as the non-treeless clone when fetching. Anything else you want to add: Also reproduced on cygwin git 2.45.1 Please review the rest of the bug report below.
