git-flow: git submodule fetch fails across-the-board

[mascguy (Christopher Nielsen)]

Git fetch fails due to timeout:

I ran into the same issue today. Perhaps because of using git:// ?

[eljakim (Eljakim Schrijvers)]

I suddenly have the same issue as well. No changes were made on our infrastructure; I am not using any proxies.

[captainproton1971 (Captain Proton)]

I have the same issue too.

[isaiah1112 (Jesse Almanrode)]

Same issue for me as well! Haven't spent much time troubleshooting yet.

[eljakim (Eljakim Schrijvers)]

I have found the underlying issue:

​https://github.blog/2021-09-01-improving-git-protocol-security-github/#no-more-unauthenticated-git

The ​git:// protocol is no longer supported by GitHub.

So ​https://github.com/nvie/gitflow/blob/develop/.gitmodules should refer to ​https:// instead of ​git://

[eljakim (Eljakim Schrijvers)]

I have tried doing this first:

git config --global url."https://".insteadOf "git://"

but that appears not to work for sub modules.

If anybody has a solution?

[sandorspruit (Sandor Spruit)]

Arriving late to the party, but the same problem here. The github repo seems to suggest the required change has already been done earlier, but reverted?

[sandorspruit (Sandor Spruit)]

Might wanna check out this webpage: ​https://github.com/petervanderdoes/gitflow-avh. Apparently, the git flow implementation referenced on macports as "git-flow" is very old and no longer supported by many tools (JetBrains IDEA and friends). No experimenting with the other one through Home-brew.

Replying to sandorspruit:

Might wanna check out this webpage: ​https://github.com/petervanderdoes/gitflow-avh

There's actually a separate port for that
