Hello, for around a year or two I do have issues which updating ghc git repository. There are actually two issues. The clone is created as recommended by ghc.dev: $ git clone --recurse-submodules https://gitlab.haskell.org/ghc/ghc.git Update is performed as recommended too: $ git pull --recurse-submodules. After some time (accumulated patches) since I update monthly or bi-monthly to test I see those two issues: 1. this is what fails first and is able to be "fixed" by running another pull: Fetching submodule utils/hsc2hs fatal: remote error: upload-pack: not our ref 0584d4fd443ac7a8e397895a79d162a55e36ef00 fatal: the remote end hung up unexpectedly fatal: remote error: upload-pack: not our ref 57d23853806add183308178663c7e22fbef2417f fatal: the remote end hung up unexpectedly fatal: remote error: upload-pack: not our ref 5361c3d9503d017d5f42daff793837a017e4f7a7 fatal: the remote end hung up unexpectedly fatal: remote error: upload-pack: not our ref e5a6da21382ae76098a4f02148504b9f79e5e2ff fatal: the remote end hung up unexpectedly fatal: remote error: upload-pack: not our ref 3373ca908ad059cbadb526e6ed1dcba5679b0d72 fatal: the remote end hung up unexpectedly fatal: remote error: upload-pack: not our ref 659eb37eb84e9cbdef226726f46a0fa5608eab5c fatal: the remote end hung up unexpectedly fatal: remote error: upload-pack: not our ref 40e1c4eb53c1e65be23e91f63139aa16111bbdf3 fatal: the remote end hung up unexpectedly fatal: remote error: upload-pack: not our ref b8ae1bf26ee0e74c3e2eeeee7fc2c7dd0dd2b0a2 fatal: the remote end hung up unexpectedly 2. this one is not-fixable, but hard to judge if this is issue at all or what. Certainly "error" is making me nervous about it. Fetching submodule utils/haddock error: cannot lock ref 'refs/remotes/origin/wip/hsyl20/dynflags': 'refs/remotes/origin/wip/hsyl20/dynflags/exception' exists; cannot create 'refs/remotes/origin/wip/hsyl20/dynflags'

This all is run on Ubuntu 20.04.x LTS pretty uptodate. The provided git is 2.25.1 there. Does anybody here have any idea why this happens? Thanks! Karel
