Trezor agent used to work on my guix system. 
Since today (I guess the last time I fully installed the manifest was a few months ago) it brings this error:

 * tag               v0.14.4    -> FETCH_HEAD
Note: switching to 'FETCH_HEAD'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at a9117c9 Bump version: 0.14.3 → 0.14.4
