In addition, be aware that Bash maintains a cache of commands it looked
up in $PATH.  Thus it may be that, say, it had cached that =E2=80=98guix=E2=
=80=99 is
really /run/current-system/profile/bin/guix.  When you pulled, it didn=E2=
=80=99t
invalidate its cache thus you kept using that old version.

The solution is to run =E2=80=9Chash guix=E2=80=9D at the Bash prompt to fo=
rce cache
invalidation (info "(bash) Bourne Shell Builtins").

HTH!
