Samba stopped working (error while loading shared libraries)

[scatleguy]

I've used Samba on my pink Pogoplug for a couple of months now and never had any problem. Until a few weeks ago, my pogoplug was acting strange. Turned out that my hostname was changed from 'Arch Linux ARM install' to 'Arch Linux ARM'. I still haven't found out how that happened, but I changed it back to 'Arch Linux ARM install' again. However, from that moment my Samba daemon refuses to start. I get the following output:
$this->bbcode_second_pass_code('', '
[root@Arch Linux ARM install ~]# /etc/rc.d/samba start
:: Starting Samba Server [BUSY]
/usr/sbin/smbd: error while loading shared libraries: /lib/libpopt.so.0: invalid ELF header
/usr/sbin/nmbd: error while loading shared libraries: /lib/libpopt.so.0: invalid ELF header
[FAIL]
')
My smb.conf looks like this:
$this->bbcode_second_pass_code('', '
[global]
workgroup = my_workgroup_name
server string = Arch Linux ARM install
netbios name = Arch Linux ARM install
security = share
load printers = no
printing = bsd
printcap name = /dev/null
disable spools = yes
log file = /var/log/samba/%m.log
max log size = 50
dns proxy = no
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=131072 SO_SNDBUF=131072 SO_KEEPALIVE

[my_share_name]
path = /media/my_path_name
read only = no
public = yes
writable = yes
force user = root
')

The path leads to an folder on a USB hard drive. Things I've already tried:
- Changing my hostname back to 'Arch Linux ARM' and also updated the smb.conf with the new hostname.
- Updated Samba through Pacman

Can anybody help me with this, because I can't figure out how to solve this.

When's the last time you did a full `pacman -Syu` ?

$this->bbcode_second_pass_quote('WarheadsSE', 'W')hen's the last time you did a full `pacman -Syu` ?

[WarheadsSE]

:facepalm:

Well at this point, it's probably best you considered trying that.

[scatleguy]

I've upgraded Samba, but that didn't help, why would you upgrade all packages (risking that those will stop working) if only Samba has a problem?

[WarheadsSE]

Arch is a rolling release, therefor we are a rolling release.

Basically at this point you are looking at one of a few problems:
- You've got corruption
- You've got newer software than the core libraries & kernel you are running on, which could likely cause errors
- Something is just royally busticated.

[scatleguy]

Will 'pacman -Syu' also update the kernel and all Arch Linux components?

[scatleguy]

Ok, I did it. But I ger an error...

Looks like the upgrade to python2-cherrypy is being blocked by plugui-git. You could try sayin 'N' to replacing cherrypy and see if it will continue. The other option would be to remove plugui-git (especially if you aren't using it) "pacman -R plugui-git"

[scatleguy]

Leaving out python2-cherrypy did the trick for the complete update. So I have done a complete 'pacman - Syu'. After some problems which I've fixed (Subsonic couldn't find java anymore and my USB drive wasn't auto mounted) all is fine now, except that Samba still refused to start. Also I got the following error after every time I used pacman:
$this->bbcode_second_pass_code('', 'ldconfig: /lib/libpopt.so.0.0.0 is not an ELF file - it has the wrong magic bytes at the start.
ldconfig: /lib/libpopt.so is not an ELF file - it has the wrong magic bytes at the start.
ldconfig: /lib/libpopt.so.0 is not an ELF file - it has the wrong magic bytes at the start.
ldconfig: /usr/lib/libpopt.so is not an ELF file - it has the wrong magic bytes at the start.
')
I found the owner of the '/lib/libpopt.so' through 'pacman -Qo libpopt.so':
$this->bbcode_second_pass_code('', ' pacman -Qo libpopt.so
libpopt.so is owned by popt 1.16-3
')
I removed popt with pacman including the dependencies (smbclient, logrotate and cryptsetup). Then I removed Samba and reinstalled it. And finally Samba started! Thanks for the tips and help!
