I noticed that 

sudo apt-get update

takes longer and longer, because i used several 

sudo apt-add-repository xxx

it seems like non ubuntu repositories are not as fast or dont have as much bandwith as the default ones.

How can i reset the repositories to the default ones, removing all the ones added by me? (not to worry, if ever need any of them i can add them later)

To delete and purge all PPAs:

The ppa-purge removes the PPA and tries to replace the installed packages with the version of the Officially Ubuntu Repositories

  1. Install ppa-purge

     sudo apt-get install ppa-purge

  2. List the commands to be used with the command below. This command does nothing than print the commands to be used in the next step

find /etc/apt/sources.list.d -type f -name "*.list" -print0 | \
while read -d $'\0' file;
do awk -F/ '/deb / && /ppa\.launchpad\.net/ {print "sudo ppa-purge ppa:"$4"/"$5}' "$file";
done
  1. Check the previous output and if all is ok, fire the purge-commands by the command below
find /etc/apt/sources.list.d -type f -name "*.list" -print0 | while read -d $'\0' file;
do awk -F/ '/deb / && /ppa\.launchpad\.net/ {system("sudo ppa-purge ppa:"$4"/"$5)}' "$file";
done

Sample output

% find /etc/apt/sources.list.d -type f -name "*.list" -print0 | while read -d $'\0' file; do awk -F/ '/deb / && /launchpad/ {print "sudo ppa-purge ppa:"$4"/"$5}' "$file"; done

You can use same command with key --remove like this:

sudo apt-add-repository --remove ppa:<user_name>/<ppa_name>

And clean them one by one. It's the safe way. Or clean their files under /etc/apt/sources.list.d/, this way not recommended but working as well.

You can also use package ppa-purge. As mentioned there.

You could try this:

  sudo add-apt-repository remove (ppa)

and it might work fine this way.

You can do it by running in terminal

sudo rm /etc/apt/sources.list.d/*

This will remove all ppa. But this will NOT remove packages installed from ppa.
