cannot run software updater on 15.10 [duplicate]

  • 772

I started my Ubuntu 15.10 and am unable to open the software updater app. I keep getting the following error

SystemError: E:Malformed line 55 in source list /etc/apt/sources.list (dist parse)

I tried purging the app and reinstalling, but still get the same error. Any suggestions?

update-manager

  1. Do the following to recreate your sources.list. Open a terminal () and type:

    sudo su

    Then recreate your sources list by copy&paste the following block into the terminal and press return once.

    cat > /etc/apt/sources.list << EOF
deb http://archive.ubuntu.com/ubuntu wily main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu wily main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu wily-updates main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu wily-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu wily-backports main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu wily-backports main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu wily-security main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu wily-security main restricted universe multiverse
deb http://archive.canonical.com/ubuntu wily partner
deb-src http://archive.canonical.com/ubuntu wily partner
EOF

    After that simply type exit to return to your normal user mode. All should be performing normally then.
