Context : I'm not able anymore to connect on my wifi network a work, however at home all is fine. I decided to check if there was some upgrades and Ubuntu tells me "failed to download repository informations". Here a little pic to illustrate. Could someone help me with this ?

In order to help, here the result of LANG=C sudo apt-get update :

You have the PPA ppa:themuso/ppa enabled but this PPA has no packages for Trusty.
Therefore remove it by executing:

sudo apt-get install ppa-purge
sudo ppa-purge ppa:themuso/ppa

To avoid the second error Failed to fetch cdrom://Ubuntu …, disable the entry deb cdrom…

sudo sed -i 's/\(^deb cdrom.*\)/#\1/' /etc/apt/sources.list

Now start

sudo apt-get update

and enjoy :)
