["Ludovic Courtès" <ludo@gnu.org>]

Hi,

Here’s the relevant syslog excerpt (this was with 1.4.0rc1) where we can
see the point where you unplugged the Ethernet connection:

It looks like the store is in a broken state, with its database not
matching its actual contents.  The ‘install-system’ procedure is
supposed to protect against that by making a backup of the database
before starting the installation and restoring it afterwards.  (It
apparently worked for me when I interrupted ‘guix system init’ by
hitting C-c.)

I wonder how that failed here.  Mathieu, ideas?

Thanks,
Ludo’.
