Upgrading to Ubuntu 17.10 (Artful Aardvark)

It's some time I don't upgrade my desktop computer, I must reckon I enjoyed the relative stability of using a LTS distribution and didn't fell the need of a twice-a-year system upgrade. Unfortunately my PC suffered of a system crash, probably because of some faulty hardware, just while updating with the result of corrupting the installed operating system beyond my capability of repairing it.
I so downloaded latest Ubuntu distribution release and started the good-old installation procedure.

No more Ubuntu-gnome long live to Ubuntu (Gnome)

I’ve been a Ubuntu-Gnome user for a long time, so I’ve been quite pleased to learn Canonical decided to stop Unity support and adopt Gnome-Shell as primary desktop manager. I so went for downloading latest Ubuntu ISO image. Once finished I prepared a bootable USB disk using Unetbootin tool, then I restarted my PC.


I started my computer from USB disk then selected the “Try Ubuntu ...” option instead of starting directly the installation program in order to collect screen-shots more easily.
After usual language and “third party” option selection I came to the installation type selection where I choose to upgrade my 16.04 installation.
Then I selected location, keyboard layout and user details …
at last installation process started.

Post installation setup

The installation type I selected should keep most of previously installed applications. In reality at my first access to the newly installed system I found most of applications I used missing. I installed some but I’m not in a hurry of installing them all since I often have my PC filled with programs I use once then I forget.

Just after install Ubuntu 17.10 comes with Gnome-shell configured to look like the (now old) Unity: with a left-sided dock and the upper-left “hot corner” disabled. I so installed gnome-tweak application to enable hot corner and also hide trashcan and drive icons from desktop. At last I visited gnome extensions page where I updated shell extension I usually use.

Mounting Samba shares

It seems every time I upgrade my computer the parameters needed to mount my NAS Samba shares changes in something. This time has been no exception. Just after the system has been installed I edited configuration file “/etc/fstab” adding the couple of configuration lines I used before (and still are working on other machines). As I tried mounting them using
Sudo mount -a
I got an odd “Host is down” error. After some searching I learned that, because of some Microsoft's protocol update, a new “version” parameter has been added. Since my NAS is quite old I has to set this parameter to “1.0”.
Here is my updated configuration:
# NAS Public share// /media/public cifs guest,uid=1000,iocharset=utf8,file_mode=0777,dir_mode=0777,sec=ntlm,vers=1.0 0 0 
# NAS Maxx share// /media/nas cifs uid=1000,credentials=/home/maxx/.smbcredentials,iocharset=utf8,sec=ntlm,file_mode=0777,dir_mode=0777,vers=1.0 0 0
