I wanted to install skype but as I installed the software, it was not correctly installed and gave an error on update that I have to disable third party repository. I want to know what's that mean, how to disable it and doe this effect the system?

Best Answer

You can disable third party repository by following any of two ways:

Execute this command in terminal
```
sudo software-properties-gtk
```
In Software Sources window go to Other Softwares .tab and delete or uncheck the repositories listed there. First delete/uncheck the repositories except first four. If it doesn't solve your issue then Uncheck the first four also. Close and run sudo apt-get update
You can also disable by following these steps:

Ubuntu Software Center > Edit > Software Sources > Other Software tab > clear/uncheck the check-boxes. Follow the same rule as given in 1st method.

3rd part repository provides additional packages/software which are generally not available in default Ubuntu repository. So disabling it would not cause any issue.

Command Line – Get List of All Repositories and PPAs into Install Script

You can show everything with:

grep ^ /etc/apt/sources.list /etc/apt/sources.list.d/*

Ubuntu – Check for and remove unused PPAs

Here is a script. Without a parameter, the script lists some infos. With --delete, the list files will be removed, if no packages are installed.

#!/usr/bin/env bash
for f in /etc/apt/sources.list.d/*.list; do
    grep -Po "(?<=^deb\s).*?(?=#|$)" "$f" | while read -r ENTRY ; do
    echo "ENTRY: $ENTRY"

    # Sanitize entry line by removing stuff between square brackets
    ENTRY=$(echo "$ENTRY" | sed 's/\[.*\] //')

        HOST=$(cut -d/ -f3 <<< "$ENTRY")

        if [ "ppa.launchpad.net" = "$HOST" ]; then
          USER=$(cut -d/ -f4 <<< "$ENTRY")
          PPA=$(cut -d/ -f5 <<< "$ENTRY")
          packageCount=$(awk '$1=="Package:" {if (a[$2]++ == 0) {system("dpkg -l "$2)}}' /var/lib/apt/lists/*"$USER"*"$PPA"*Packages 2>/dev/null | awk '/^ii/' | wc -l)
          echo "PPA: ppa:$USER/$PPA"
          echo "FILENAME: $f"
          echo "$packageCount package(s) installed"
          if [ "$packageCount" -eq 0 ] && [ "$1" == "--delete" ]; then
            sudo rm "$f" && echo "$f deleted"
          fi
          echo
        else 
          USER=$(cut -d/ -f3 <<< "$ENTRY")
          PPA=$(cut -d/ -f4 <<< "$ENTRY")
          packageCount=$(awk '$1=="Package:" {if (a[$2]++ == 0) {system("dpkg -l "$2)}}' /var/lib/apt/lists/*"$USER"*Packages 2>/dev/null | awk '/^ii/' | wc -l)
          echo "REPOSITORY: $USER/$PPA"
          echo "FILENAME: $f"
          echo "$packageCount package(s) installed"
          if [ "$packageCount" -eq 0 ] && [ "$1" == "--delete" ]; then
            sudo rm "$f" && echo "$f deleted" 
          fi
          echo
        fi
    done
done

Copy the code above in a new file, e.g.:

mkdir -p ~/bin
nano ~/bin/checkPPAs

Make the script executable

chmod +x ~/bin/checkPPAs

And run it with

~/bin/checkPPAs

to list all repositories and the number of installed packages.

Start the script with

~/bin/checkPPAs --delete

to remove the list files.
