How do I find all of my software sources?

Solution 1:

Software repositories as used for apt-get are set in /etc/apt/sources.list.

apt-add-repository adds additional repositories in /etc/apt/sources.list.d/*.list. Note that the extension is .list too. To find all occurences of these *.list files, run the next command in a terminal window:

find /etc/apt/ -name '*.list' -ls -exec cat {} \;

It will provide all useful information regarding software repositories used by apt. If this list is very long, and a file is preffered, use the next command to create a file in the current directory, named repositories.txt:

find /etc/apt/ -name '*.list' -ls -exec cat {} \; > repositories.txt

To post this list on Askubuntu, go to http://paste.ubuntu.com/ and paste the list in the big text field. Submit the form by pressing "Paste!" and copy the URL from the location bar (which should look like "http://paste.ubuntu.com/566454/"). Finally, paste this URL in your question.

Solution 2:

If you want a GUI, it’s any of these:

• Update Manager → Settings,
• Software Centre → Software Sources,
• Synaptic Package Manager → Repositories.
