Updated October 19 2011 to use never version drivers. Works on Debian and LMDE too.

Tired of wasting money buying ink-jet cartridges that run out without even using them, I recently bought a Canon ImageCLASS MF4270 Laser Printer. It is also a multifunctional device with scanner, copier and fax.

Canon now provides .deb files for easy installation of their ImageCLASS MF4270 printer on Ubuntu Linux (or other debian based distributions). Unfortunately they are only providing them for i386 (32 Bit Systems)

For RPM based distributions however, they do provide 64-Bits installation files.

Using alien I converted these 64bit RPM to deb.

I am making them available here for your convinience:

• cndrvcups-common_2.20-2_amd64.deb
• cndrvcups-ufr2-us_2.20-2_amd64.deb

Dont forget to set the device URI to: socket://xxx.xxx.xxx.xxx:9100 (x’s being the IP address of printer)

Finally we have a native 64bit Flash 11. It is working very well, I highly recommend it.

Before installing it, make sure that previous versions of Flash and nspluginwrapper are uninstalled.

Download it from:
http://download.macromedia.com/pub/labs/flashplatformruntimes/flashplayer11/flashplayer11_b1_install_lin_64_071311.tar.gz
untar, copy and link  libflashplayer.so to /usr/lib/mozilla/plugins by doing the following in the terminal. (make sure you close Firefox first)

tar zxvf flashplayer11_b1_install_lin_64_071311.tar.gz sudo cp libflashplayer.so /usr/lib/mozilla/plugins/ sudo ln -sf /usr/lib/mozilla/plugins/libflashplayer.so /usr/lib/firefox-addons/plugins/ sudo ln -sf /usr/lib/mozilla/plugins/libflashplayer.so /usr/lib/xulrunner-addons/plugins/

Done!

Or, alternatively (you should always read and understand scripts before running them) you can do this installation just by copying and pasting the following in the terminal:

wget https://blog.alejandrocuervo.com/downloads/flash_x64_en.sh && sudo chmod +x flash_x64_en.sh && sudo sh ./flash_x64_en.sh

This script will install Native 64 Bit Flash 11 and will also remove previous versions of flash and “nspluginwrapper”
Note: If you just want to see the code for the script, it is available here:
https://blog.alejandrocuervo.com/downloads/flash_x64_en.sh

Installing Thunar in gnome causes Nautilus to show a “the location is not a folder” error.

The problem is a thunar dependency called exo-utils.

Removing exo-utils also removes thunar. Some of us need to have both thunar and nautilus installed in gnome:
Since the problem is exo-utils, I have built a thunar .deb without the exo-utils dependency.

Here is how for 64bit:

wget http://launchpadlibrarian.net/69753654/thunar_1.2.1-3ubuntu2_amd64.deb
dpkg-deb -x thunar_1.2.1-3ubuntu2_amd64.deb tmpdir
dpkg-deb --control thunar_1.2.1-3ubuntu2_amd64.deb tmpdir/DEBIAN
gedit tmpdir/DEBIAN/control

Remove ‘exo-utils’ from the ‘Depends’ line and save

dpkg -b tmpdir thunar_1.2.1-3ubuntu2_amd64-no_exo-utils_dependency.deb
sudo apt-get remove exo-utils
sudo dpkg -i thunar_1.2.1-3ubuntu2_amd64-no_exo-utils_dependency.deb
sudo apt-get -f install

Or

Download the package from here:

https://blog.alejandrocuervo.com/downloads/thunar_1.2.1-3ubuntu2_amd64-no_exo-utils_dependency.deb

Done!

Be sure to enable the “Source Code” repositories first.

sudo aptitude build-dep gnucash
sudo aptitude install texinfo subversion intltool libdbi0-dev libdbd-{sqlite3,pgsql,mysql} guile-1.8 guile-1.8-dev doxygen libdbi0-dev libdbd-{sqlite3,pgsql,mysql}

cd /usr/share/guile/1.8
sudo ln -s ../../slib slib
sudo guile -c "(use-modules (ice-9 slib)) (require 'new-catalog)"

cd ~/gnucash-2.4.0/

./configure --prefix=$HOME/stable/gnucash --enable-debug --enable-doxygen --enable-error-on-warning --enable-compile-warnings --enable-dbi
make all install

and finally, run it

~/stable/gnucash/bin/gnucash

Done!
