Tried again with "strace -f" and got this:

stat("/home/sdb/.guix-profile/libexec/git-core/ssh", 0x7ffe26617620) =
-1 ENOENT (No such file or directory)
stat("/gnu/store/6ff29rxibnfzabp17qj3mzpc8jggrmsn-profile/bin/ssh",
0x7ffe26617620) = -1 ENOENT (No such file or directory)
stat("/gnu/store/6ff29rxibnfzabp17qj3mzpc8jggrmsn-profile/sbin/ssh",
0x7ffe26617620) = -1 ENOENT (No such file or directory)

stat("/run/current-system/profile/sbin/ssh", 0x7ffe26617620) = -1 ENOENT
(No such file or directory)
close(14)                               = 0

So installing ssh might be a good idea >D

Solved! :D
