14.04: can'topen update manager and can't update

[micknotten]

Hi,

I'm using 14.04 on my old laptop. Now, if I'm trying to update, the terminal returns this:

mick@zilverendoos:~$ sudo apt-get update
[sudo] password for mick:
E: Type 'apt-get' op regel 2 in bronlijst /etc/apt/sources.list.d/mono-xamarin.list is onbekend
E: De lijst van bronnen kon niet gelezen worden.


In English, this means: E: Type 'apt-get'in line 2 in sourcelist /etc/apt/sources.list.d/mono-xamarin-listis unknown
E: source list could not be read

If I try to open the update-manager there is no responce. Can someone help me?

Thanks,

Mick

Post the output for the mono-xamarin.list file.
from a terminal copy the output from

cat /etc/apt/sources.list.d/mono-xamarin.list
It says line 2 has a problem ,but we won't know until we see what line 2 is.

It returns this:

mick@zilverendoos:~$ cat /etc/apt/sources.list.d/mono-xamarin.list

apt-get update



mick@zilverendoos:~$

It seems some where when you added the mono repo, something was done wrong.
I would recommend removing that file and try making a new one.

sudo rm /etc/apt/sources.list.d/mono-xamarin.list
Following the directions from mono
(see here for reference:http://www.mono-project.com/docs/getting-started/install/linux/)
Enter each command one at a time
First add the key

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
Then remake the source file.

echo "deb http://download.mono-project.com/repo/debian wheezy main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list
And then run the update command so that the new source can be added to your package lists.

sudo apt-get update

For double measure you can re-run the command I posted earlier and this time it should say
deb http;//download.mono-project.com/repo/debian wheezy main

Hope that helps

Hi deadflowr,

thanks for your responds! The second line (echo..) didn't work, but it's updating now, so I think the problem 's solved!

Thank you very much, amazing!

Chhers,

I think my spacing between echo and the "deb stuff" was off.
Fixed that.
echo is a command, but if commands aren't properly spaced the command won't be read correctly, or at all.
It seems I posted echo"deb, instead having a space between the two echo "deb.
