Upgrading to Ubuntu Linux 12.04 LTS Precise Pangolin

-
Now that the latest LTS is out, I thought the time is ripe to upgrade.
I downloaded via BitTorrent, burned the image to a CD, then booted the CD and chose "Install." I was able to make some install choices while files were being copied and downloaded, left, and when I came back all I had to do was reboot.
Instagram Nashville: Ubuntu Install
On reboot, I had the unpleasant surprise to discover that my login was not functional. I got in via a Guest session, accessed System Settings, changed my password by giving the old password for root, logout and login again with the new password.
Once "in" I ran the command to encrypt my home folder and stored the key elsewhere. I had to reinstall Opera and a few other proggies from the Software Center but luckily, the old settings were recovered.
Software Sources - Select Best Server
The default repos for this distro were painfully slow, so I ran the good old Software Source (software-properties-gtk) "fastest repo" routine to choose the fastest. You can run it by itself, from the Edit menu of the Software Centre or you can "unhide it" as follows:
mkdir ~/.local/share/applications  # to make sure directory exists
cp /usr/share/applications/software-properties-gtk.desktop ~/.local/share/applications/
sed -i s/NoDisplay=true/NoDisplay=false/ ~/.local/share/applications/software-properties-gtk.desktop
The app will reappear after you re-log in.
First, I looked in the sources.list generator and used it for a few more repos:

Not as pretty as a separate file in the sources.d directory, but good enough.
I also easily adjusted my monitors as I wanted, using "Displays" in the System Settings. I checked if the Wacom tablet functioned as expected and it did.  I will check the fingerprint stuff later. In Oneiric Ocelot 11.10 the tablet stopped working after I got the fingerprint scanner to behave.

Medibuntu from previous instructions then install libdvdcss2 for DVD playback. However, keep in mind that for some reason it is incredibly slow and tends to hang, which is why I will probably disable it.

I also downloaded and installed TrueCrypt. This involved:
  1. Downloading the actual program, its digital sig and importing TC sig.
  2. I discovered that somehow gpg settings and my key did not survive the upgrade so I imported my old key, then signed TC key and verified it (see handbook):
    gpg --import TrueCrypt-Foundation-Public-Key.asc
    gpg --edit-key F0D6B1E0
    >trust
    to marginal (using choice number 3)
    and then
    >sign
    I sign it with the above generated key and my password.
    gpg --verify truecrypt-7.1a-linux-x64.tar.gz.sig truecrypt-7.1a-linux-x64.tar.gz
  3. Uncompressing and running results in
    Installing package...
    usr/bin/truecrypt
    usr/bin/truecrypt-uninstall.sh
    usr/share/applications/truecrypt.desktop
    usr/share/pixmaps/truecrypt.xpm
    usr/share/truecrypt/doc/License.txt
    usr/share/truecrypt/doc/TrueCrypt User Guide.pdf
  4. Victory!

Transmission Remote GUI was next, and after uncompressing it went to /usr/local/bin where stories are made.

UbuntuOne error
For UbuntuOne I signed up for a new account, but unfortunately my old computer name was recognized as attached to the previous account, which I suspect is the reason for the error above. I'll sign up with the old account later, when I can find it.

To disable IPv6, echo at the end of /etc/modprobe.d/blacklist.conf: blacklist ipv6

I then intended to install a number of apps I could no longer see but for some reason apt-get was locked, so I rebooted. On reboot, apt-get autoremove went on for a minute or so removing obsolete crap, then processing triggers, and finally spewing

I'm not sure how to fix it, we'll see later.

For TV, I installed HDHomeRun Config GUI from repos as well as hdhomerun_config. Scanning with a simple indoor antenna results in the following channels:

CFMT (multiculti) is the weakest, but the others are quite alright. Channel flipping is a bit time-consuming with their GUI as it scans unless you enter it directly. Using a more advanced application might require installing dvbhdhomerun to masquarade as DVB:
sudo add-apt-repository ppa:tfylliv/dvbhdhomerun
sudo apt-get update
sudo apt-get install dvbhdhomerun-dkms dvbhdhomerun-utils
sudo service dvbhdhomerun-utils start

SOPcast is best served with TVmaxe. I wouldn't 
sudo add-apt-repository ppa:venerix/blugsudo add-apt-repository ppa:ferramroberto/sopcast
sudo apt-get update
sudo apt-get install tv-maxe sopcast-player

gksudo gedit /usr/share/sopcast-player/lib/vlc_1_0_x.py
search for # Decorator for callback methods
replace below with callbackmethod=
ctypes.CFUNCTYPE(None, ctypes.POINTER(Event), ctypes.c_void_p)

    Tribler allows for some limited P2P TV as well:
sudo add-apt-repository ppa:webupd8team/tribler
sudo apt-get update
sudo apt-get install tribler
 
For accessing network shares, I could follow the old instructions or simply go to the Connect to Server interface (in the menu) and fill in the needed info. I could then simply bookmark the drives or edit fstab so that they are mounted automatically.

To get the cube:
  1. sudo apt-get install compizconfig-settings-manager # mine was already there
  2. search for ccsm, then launch it
  3. Under 'Desktop', simply tick the checkbox beneath the 'Desktop Cube' plugin (for my laptop with an Intel card it's not showing, being blacklisted). In the dialog that pops up, choose 'Disable Desktop Wall'
  4. Enable "rotate cube" plugin under 'Desktop'
  5. For a perfect cube, General > General Options > Desktop Size and change 'Horizontal Virtual Size' to '4', and 'Vertical Virtual Size' to '1' (originally 2, 2, 1).
To re-enable hibernate, type first sudo pm-hibernate to see if your system supports it.
gksudo gedit /var/lib/polkit-1/localauthority/50-local.d/hibernate.pkla
then paste 
[Re-enable Hibernate]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes
then restart. 'Suspend' will disappear.
To install a bunch of codecs:
sudo apt-get install libxine1-ffmpeg gxine mencoder totem-mozilla icedax tagtool easytag id3tool lame nautilus-script-audio-convert libmad0 mpg321
To install the System Load Indicator:
sudo add-apt-repository ppa:indicator-multiload/stable-daily
sudo apt-get update
sudo apt-get install indicator-multiload
Turn off recording history in Privacy (System Settings) and delete past history. I see no use for it.
By default, Ubuntu hides some apps in the Startup Applications. Get them back with
sudo sed -i 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop
I don't bother with a screen saver, but if you do, try Xscreensaver after removing gnome-screensaver. To prevent it from starting when watching a movie, install caffeine with ppa:caffeine-developers/ppa | caffeine python-glade2.
Finally, I wish I could tweak the Startup menu with the old Startup-Manager, but it's not showing up.
Well, that's about it. I might add more stuff and clean up this later; or maybe not :)
