I've just upgraded to Ubuntu 17.10 and am missing the Ubuntu Dock settings, i.e. in gnome-control-center the dock settings are blank:

enter image description here

I think I might be missing the "ubuntu-dock" package, but can't find this anywhere in the software centre.

Also the gnome-control-center was completely missing after the update, and I had to install this separately - not sure if this is related.

I think this is different from ubuntu-dock settings not accessible in gnome-control-center by default because changing the type of GNOME session doesn't fix the problem. If I go for GNOME* I get no Dock settings section at all, and if I got for Ubuntu* I get the blank Dock settings section described above.

Output of apt-cache policy gnome-shell-extension-ubuntu-dock:

rob@rob-pc:~$ apt-cache policy gnome-shell-extension-ubuntu-dock

I seem to have lost the ability to mount audio cds - maybe since upgrading to 17.04? - DVDs mount OK.

Nautilus says "Unable to access "Audio Disk" - Location is not mountable".

Trying to mount manually using sudo mount /dev/sr0 /media/cdrom1/ gives me:

mount: /dev/sr0 is write-protected, mounting read-only
mount: /dev/sr0: can't read superblock

dmesg | tail then gives me:

[  125.618809] sr 4:0:0:0: [sr0] tag#2 CDB: Read(10) 28 00 00 00 00 00 00 00 02 00

[  127.326804] squashfs: SQUASHFS error: unable to read squashfs_super_block

Also tried sudo mount /dev/sr0 /media/cdrom1/ -t iso9660 leading to: 

mount: /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
   missing codepage or helper program, or other error

   In some cases useful info is found in syslog - try
   dmesg | tail or so.

And dmesg | tail

Not sure where to go from here so grateful for suggestions.

Thanks a lot
