Make fails to clone submodules un Ubuntu 20.04

[jordancarlin]

On Ubuntu 20.04 I get the following error message when running make:

error: Server does not allow request for unadvertised object 26f7004bf73c421c3fd5e5a6ccf470d05337b435

It seems to be related to the version of git. Ubuntu 20.04 comes with git 2.25.1. If I build and install the latest version of git then this problem goes away. Seeing as Ubuntu 20.04 is still supported, it would be ideal if this worked with the built in version of git.

The problem seems to have been introduced by #1608.

I think that it's the same issue as discussed/explained here?

• git submodule update fails #1654 (comment)

Note that Ubuntu 20.04 is no longer one of the distros used by the CI builds:

• riscv-gnu-toolchain/.github/workflows/nightly-release.yaml

  Lines 45 to 52 in a33dac0

  	build:
  	needs: activity-check
  	if: needs.activity-check.outputs.stale != 'true'
  	runs-on: ${{ matrix.os }}
  	strategy:
  	matrix:
  	os: [ubuntu-22.04, ubuntu-24.04]
  	mode: [newlib, linux, musl, uclibc]

However, addressing the shallow checkout problem mentioned in the first link will probably help with 20.04?

You can solve it by typing git config --global protocol.version 2 in the terminal. For detailed reasons, please see: Error Fetching Submodule in RISC-V GNU Toolchain: Server Does Not Allow Request for Unadvertised Object.

Thank you for the information. Very informative link!

That didn't make any difference for me:

git config --global protocol.version 2

git clone https://github.com/riscv-collab/riscv-gnu-toolchain issue-1663

cd issue-1663

How did you do this?
I tried this to no avail:

wget https://www.kernel.org/pub/software/scm/git/git-2.48.1.tar.xz
tar xvf git-2.48.1.tar.xz
cd git-2.48.1/
./configure --prefix=`pwd`/installed-tools
make
...
    GEN git-mergetool--lib
    GEN git-sh-i18n
    GEN git-sh-setup
    CC scalar.o
    LINK scalar

    GEN git-gui

Closing due to lack of updates and given that it's effectively a duplicate of this:
