Yes, it is similar to https://bugs.launchpad.net/bugs/1906915 and https://bugs.launchpad.net/bugs/1882589, but I don’t think it is completely the same.

Using `git-remote-bzr` from the openSUSE package breezy-3.3.4-1.3.x86_64.

Are you logged into Launchpad? Git seems to eat the prompt and then times out. The following works for me as a workaround:

bzr branch https://code.launchpad.net/pyexiv2 pyexiv2.bzr
git clone bzr::pyexiv2.bzr pyexiv2.git

Does being logged mean running `bzr launchpad-login`? If so, then yes.

And yes, bzr fast-export works just fine (so I have
https://git.cepl.eu/cgit/toys/pyexiv2/), but I hoped to get all
those branches at least like special remotes.

Actually, with explicit `bzr launchpad-login` the situation is worse:

```
tumbleweed-pkg~$ bzr launchpad-login
mcepl
tumbleweed-pkg~$ /tmp/
tumbleweed-pkg/tmp$ git clone bzr::lp:pyexiv2
