mount boot unknown filesystem type 'ext2'

Problem :

When I execute : mount /boot/, I have the following :
mount: unknown filesystem type 'ext2'

In my /etc/fstab, I have  :

 /dev/sda1               /boot           ext2            defaults        1 2

Solution :

Add a journal to /dev/sda1 :

tune2fs -O has_journal /dev/sda1

Then modify ext2 en ext3 in /etc/fstab.

 /dev/sda1               /boot           ext3            defaults        1 2

So, now you can make a mount : mount /boot

Install Google Chrome on Ubuntu 9.10

I've found a post about installing Chrome on Ubuntu.I test it and it works ! So I put it here :


November 2nd, 2009
This post was written when Chrome was still not available for Linux. Chromium was the only option then. Now that Google Chrome is available, just go to Google's website and download the browser directly.

Add to your sources list.
$ sudo gedit /etc/apt/sources.list

You may substitute jaunty, intrepid, hoary for other distributions.

Su command permission denied

If you write su with the good password on your terminal and you have always the error "permission denied".It's probably because you user have not the group wheel.
So the only thing you have to do is :

gpassw -a user wheel

Why ?

The wheel group is a group which limits the number of people who are able to su to root. This usually consists of a group named “wheel” and a set of users that are permitted to use the utility ’su’ in order to change to root.
