package samba4 4.0.3+dfsg1-0.1ubuntu1 throws exception when encountering invalid config option

[Clay Neitz]

I had samba installed on my system before

My computer had been off for a couple days then I started it and could not access files over the network.

Tried to run samba locally and it said not installed, please install.

Switched to root access and appeared to be installing but gave an error code (1)

The option "security = share" isn't supported anymore. The package should tell the user as much instead of throwing an unhelpful exception.

[Andreas Moog (ampelbein)]

Thanks for the report. The cause of the issue is that you have a invalid /etc/samba/smb.conf file, the option "security = share" is deprecated. The bug, however, is that, instead of telling you that, samba4 decides to just throw up and confront you with an exception. The package maintainers will have to deal with that part.

To get your samba installation repaired, I suggest setting "security = user", then running "testparm /etc/samba/smb.conf" and look for other reports of invalid/deprecated options. After you finished that, run "sudo apt-get -f install". That should clear your issue.

[Anton Piatek (anton-piatek)]

I thnik I hit this issue trying to upgrade from 13.04 to 13.10 and it completely killed the upgrade. I simply purged the samba4 package and reinstalled, but a non-technical user would be completely stumped and worried about the upgrade killing their box.

absolutely Fresh installed Ubuntu.

Did as Andreas Moog said:

As you can see, I have quite a lot of puke for output. My system:
amd cpu/chipset/gpu
Ubuntu 13.10, upgraded from fresh install of 13.04. In use for several months
Kernel 3.12 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-saucy/
This is my first install of anything related to samba. I attempted a stand-alone install.
You can see that upon seeing a list of suggested packages I cancelled install and attempted to include those. Some don't even exist! I consider that to be more puke. (Terminal output from copy/paste was cut off as well!) I tried again with the offending packages omitted from the install list.

After the error occurred, I tried apt-get update, and upgrade. Then apt-get install -f (Also it's 4am, dpkg -i was NOT want I wanted.)
No Joy.
And without further ado, terminal puke:

This can't be right. Please move this comment to a different thread, but I think it is greatly related. After the fiasco above, I decided to try installing the package samba (no4). Have a look at the packages it wants to remove for me. mplayer? I use that one! software-center? That one seems important. vlc-plugin-pulse. GET THE HELL OUT! system-config-printer-common. Not that I have a printer, but, don't touch that! kubuntu-debug-installer??? I don't know how that one ever got installed on my system, alond with kde-runtime, but it wasn't installed with the above proceduure, and shouldn't be touched now. This is more of a bug in apt-get but it seems to me these packages are causing it.
