Hi Simon,

The storm is over and users no longer complain.





I will be careful for the next user.

Thank you again  for your efforts and advices.

It seems that all the problems came from a disorder in the NAS permissions. I didn't mention that the home is hosted by a NAS. I guess this disorder disturbed first the sssd and mkhomedir and since guix.

Hi,

Sorry for the late reply.

I hope the message "user with UID 255759 not found" has nothing to do
with the issue.

Well, this message comes from the Guix daemon (see nix-daemon.cc file):

         /* Open the store. */
         store = std::shared_ptr<StoreAPI>(new LocalStore(reserveSpace));

        if (userId != (uid_t) -1) {
             /* Create the user profile.  */
             struct passwd *pw = getpwuid(userId);
             if (pw != NULL && pw->pw_name != NULL)
                 store->createUser(pw->pw_name, userId);
             else
                 printMsg(lvlInfo, format("user with UID %1% not found") % 
userId);
        }


Hum, that’s not clear for me.  The daemon is a beast… Maybe this has an
impact.  For sure, aside Guix, I think it would be better to fix it. :-)

Well, I do not know why but this other message:

     > When I create the user home dir manually, the "guix pull" work's fine.
     > So the trouble could come from a disorder with the automatic home dir
     > creation.

     > I wish it's the right track. I keep digging.

spots the light on UID. :-)
