Ajuda: not known on line 54 in source list /etc/apt/sources.list

[Filipe85]

i have had this error message every time i try to update, or install an aplication:


``Could not initialize the package information

An unresolvable problem occurred while initializing the package information.

Please report this bug against the 'update-manager' package and include the following error message:

'E:Type 'usage:' is not known on line 54 in source list /etc/apt/sources.list, E:The list of sources could not be read.'
``

the problem strated after i tried to install cairo from here:

my source.list:

You should remove these lines from your sources.list file, I think, the last of which is one of the two identical lines, or you will get an error about duplicate lines.

I have no idea where all that rubbish came from, but it is certainly not needed in the sources.list file.
Use
gksudo gedit /etc/apt/sources.listto edit the file, but back it up first, just in case.
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

This entire section is garbage and does not belong in sources.list, you may safely delete it:


usage: sudo -h | -K | -k | -L | -V
usage: sudo -v [-AknS] [-p prompt]
usage: sudo -l[l] [-AknS] [-g groupname|#gid] [-p prompt] [-U username] [-u
username|#uid] [-g groupname|#gid] [command]
usage: sudo [-AbEHknPS] [-C fd] [-g groupname|#gid] [-p prompt] [-u
username|#uid] [-g groupname|#gid] [VAR=value] [-i|-s] [<command>]
usage: sudo -e [-AknS] [-C fd] [-g groupname|#gid] [-p prompt] [-u
username|#uid] file ...

/etc/apt/sources.list is an important system file! I do not recommend editing this file directly in the future; you can use the GUI Software Sources application to safely add PPA's.
