bug#50512: Errors reported by make check

[Alberto EFG]

Hey,

Yesterday I was building Guix from a latop with Ubuntu 20.04 and I got
3 Fails.

I also got a (probably unrelated) error when doing ~guix environment guix 
--pure~

#+begin_src 
Command 'lesspipe' is available in the following places

    /bin/lesspipe
    /usr/bin/lesspipe
    The command could not be located because '/usr/bin:/bin' is not included in 
the PATH environment variable.
#+end_src






The test-suite.log is attached
