Hi Guix,
I recently tried re-entering an older environment via:
$ guix describe
Generation 128 Jul 06 2022 14:50:39 (current)
guix 17892c5
repository URL: https://git.savannah.gnu.org/git/guix.git
branch: master
commit: 17892c5f9c5c5c93325884834a58cc2a4fafa51f
sfl-packages 6385881
repository URL: https://gitlab.com/Apteryks/sfl-guix-channel
branch: master
commit: 6385881124429016f750b0f562b70e07f592275e
$ guix time-machine -C channels.scm -- shell
with in the current directory the project manifest file:
--8<---------------cut here---------------start------------->8---
(packages->manifest
(map specification->package
(list
;; General utilities.

--8<---------------cut here---------------end--------------->8---
and the channels.scm file:
--8<---------------cut here---------------start------------->8---
(list (channel
(inherit %default-guix-channel)
(commit
"ceeb2bfcaeb4380e01d26c8425e28b94ac13558a"))) ;2022-06-07
--8<---------------cut here---------------end--------------->8---
and was surprised to be greeted with the following error:
--8<---------------cut here---------------start------------->8---
(repl-version 0 1 1)
(exception %exception (non-self-quoting 140737300283024 "#<&message message: \"unsupported manifest format\">"))
/var/log/guix/drvs/j8/0wjfx7s7nxhcn0wjxfysnnv2knx0c1-guix-package-cache.drv (END)
--8<---------------cut here---------------end--------------->8---
What does it mean? Which manifest is it referring to?
Thanks,
Maxim

Commit 4ff12d1de7cd617b791996ee7ca1240660b4c20e introduced that bug,
which was fixed in c9fbd40785a99e13a59d8e530830ce85220a9871:
https://issues.guix.gnu.org/56441
‘guix describe’ should show that you’re using a commit in that range.
The solution is to run ‘time-machine’ from a commit outside that range,
for instance with:
guix time-machine -- time-machine -C channels.scm -- whatever
:-)
