"git clone git://git.launchpad.net/<anything>" fails with git 2.26.0

[Colin Watson]

  $ git --version
  git version 2.26.0
  $ git clone git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/focal
  Cloning into 'focal'...
  fatal: remote error: Parameters must have values

The particular repository doesn't matter (e.g. git://git.launchpad.net/germinate does the same thing). Possibly due to lack of protocol 2 support, although I didn't think it was meant to be a backward-compatibility break like this.

[Andy Whitcroft (apw)]

2.26.0 is in Debian unstable already.

Ioana, I'm afraid this fix wasn't quite enough. Could you have another look on Monday, please?

$ git clone git://git.qastaging.paddev.net/~cjwatson/germinate/qastaging germinate
Cloning into 'germinate'...
fatal: remote error: Illegal request parameters

[Colin Watson (cjwatson)]

Slightly more correct and useful:

$ GIT_TRACE_PACKET=1 git clone git://git.qastaging.paddev.net/~cjwatson/germinate/+git/qastaging germinate
Cloning into 'germinate'...

16:51:03.939203 pkt-line.c:80 packet: clone< ERR Illegal request parameters
fatal: remote error: Illegal request parameters

Fix deployed to production today.
