Error PPA: Failed to fetch


When i try add
sudo apt-get install git python-virtualenv mercurial libxml2-dev libxslt-dev python-dev libsqlite3-dev --fix-missing
i get:
2 upgraded, 0 newly installed, 0 to remove and 4 not upgraded. Need to get 12.5 MB of archives. After this operation, 932 kB of additional disk space will be used. Do you want to continue? [Y/n] y
and after this:
Failed to fetch (many times)
How can i repair this?


Did you run apt-get update first? Can you paste the output log please (you can remove the duplicate Failed to fetch lines) and also try curl


Thanks, I forgot to do
sudo apt-get update
