Install Systemtap

Ubuntu

Add “Ubuntu ddebs” source file, and paste the following command in the command line:


codename=$(lsb_release -c | awk  '{print $2}')
sudo tee /etc/apt/sources.list.d/ddebs.list << EOF
deb http://ddebs.ubuntu.com/ ${codename}      main restricted universe multiverse
deb http://ddebs.ubuntu.com/ ${codename}-security main restricted universe multiverse
deb http://ddebs.ubuntu.com/ ${codename}-updates  main restricted universe multiverse
deb http://ddebs.ubuntu.com/ ${codename}-proposed main restricted universe multiverse
EOF

In Ubuntu 11.10, delete “universe, multiverse”, and change it to:


codename=$(lsb_release -c | awk  '{print $2}')
sudo tee /etc/apt/sources.list.d/ddebs.list << EOF
deb http://ddebs.ubuntu.com/ ${codename}      main restricted
deb http://ddebs.ubuntu.com/ ${codename}-security main restricted
deb http://ddebs.ubuntu.com/ ${codename}-updates  main restricted
deb http://ddebs.ubuntu.com/ ${codename}-proposed main restricted
