[Bug 1292548] Re: Standalone Server: Update from Samba 2:3.6.18-1ubuntu3.1 (saucy) to 2:4.1.3+dfsg-2ubuntu3 (trusty) breaks access to the server

[Raoul Bhatia]

Dear Robie,

actually, it is quite easy to reproduce during an update from saucy to
trusty and i suspect that this bug will even strike when you do a clean
trusty install.

Nevertheless, i reproduced this issue with a fresh saucy install:

1. install saucy using http://at.mirror.archive.ubuntu.com/ubuntu/dists/saucy/main/installer-amd64/current/images/netboot/mini.iso
2. install openssh-server and samba-server during installation (via tasksel?)
3. reboot and verify samba status:
# root at ubuntu:~# smbstatus

Samba version 3.6.18
PID     Username      Group         Machine
-------------------------------------------------------------------

Service      pid     machine       Connected at
-------------------------------------------------------

No locked files

4. add a user and view list the available shares
# root at ubuntu:~# smbpasswd -a ubuntu
New SMB password:
Retype new SMB password:


# root at ubuntu:~# smbclient -L \\localhost -U ubuntu
Enter ubuntu's password:
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.6.18]

        Sharename       Type      Comment
        ---------       ----      -------
        IPC$            IPC       IPC Service (ubuntu server (Samba, Ubuntu))
        print$          Disk      Printer Drivers
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.6.18]

        Server               Comment
        ---------            -------
        UBUNTU               ubuntu server (Samba, Ubuntu)

        Workgroup            Master
        ---------            -------
        WORKGROUP            UBUNTU


5. do-release-upgrade -d (remove obsolete packages; reboot)

6. verify samba access (FAILS!)

Please let me know in case you require this system as a KVM/QEMU disk image.

Cheers,
