apt build-dep fails, unable to locate source package, despite deb-src lines present in the /etc/apt/sources.list.d folder
Solution 1
You need to uncomment the deb-src
lines in the main sources file /etc/apt/sources.list
, not the extra files in /etc/apt/sources.list.d
For example, change:
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
deb http://gb.archive.ubuntu.com/ubuntu/ xenial main restricted
#deb-src http://gb.archive.ubuntu.com/ubuntu/ xenial main restricted
to
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
deb http://gb.archive.ubuntu.com/ubuntu/ xenial main restricted
deb-src http://gb.archive.ubuntu.com/ubuntu/ xenial main restricted
Then update the local database:
sudo apt update
and proceed :)
Solution 2
software-properties-gtk
option "Source code"
From the GUI, you can run:
software-properties-gtk
then under the "Ubuntu Software" tab click "Source code":
This has added some deb-src
lines under /etc/apt/sources.list
, and now I can do sudo apt-get build-dep <package>
.
Tested on Ubuntu 16.04 to 18.04.
CLI method
sudo sed -Ei 's/^# deb-src /deb-src /' /etc/apt/sources.list
sudo apt-get update
Tested on the Ubuntu 18.04 Docker image. After this change, I can successful do for example:
sudo apt-get build-dep hello
and before the change it failed with the error:
E: You must put some 'source' URIs in your sources.list

I ran
sudo apt-get build-dep emacs24
and it returned the error:Reading package lists... Done E: Unable to find a source package for emacs24
Now I know the usual advice in this situation, that is, uncomment
deb-src
lines in the.list
files in your/etc/apt/sources.list.d
folder (per https://unix.stackexchange.com/questions/158395/apt-get-build-dep-is-unable-to-find-a-source-package). I've tried this though! Every single file in my/etc/apt/sources.list.d
folder has any deb-src lines in it uncommented. I even ransudo apt-get update
after uncommenting these lines! So please help me. Here are the contents of my/etc/apt/sources.list.d
folder, if you need the contents of any of these files, just say and I'll be happy to provide them.$ ls /etc/apt/sources.list.d alexlarsson-ubuntu-flatpak-xenial.list alexlarsson-ubuntu-flatpak-xenial.list.save cpick-ubuntu-hub-xenial.list cpick-ubuntu-hub-xenial.list.save damien-moore-ubuntu-codeblocks-stable-xenial.list damien-moore-ubuntu-codeblocks-stable-xenial.list.save danielrichter2007-ubuntu-grub-customizer-xenial.list danielrichter2007-ubuntu-grub-customizer-xenial.list.save docker.list docker.list.save dolik-rce-ubuntu-upp-xenial.list dolik-rce-ubuntu-upp-xenial.list.save dotnetdev.list dotnetdev.list.save gnome3-team-ubuntu-gnome3-staging-xenial.list gnome3-team-ubuntu-gnome3-staging-xenial.list.save gnome3-team-ubuntu-gnome3-xenial.list gnome3-team-ubuntu-gnome3-xenial.list.save google-chrome.list google-chrome.list.save google-earth.list google-earth.list.save icons.list icons.list.save jonathonf-ubuntu-golang-xenial.list jonathonf-ubuntu-golang-xenial.list.save kubuntu-ppa-ubuntu-backports-xenial.list kubuntu-ppa-ubuntu-backports-xenial.list.save mmk2410-ubuntu-eclipse-ide-java-xenial.list mmk2410-ubuntu-eclipse-ide-java-xenial.list.save mono-jenkins.list mono-jenkins.list.save mono-xamarin.list mono-xamarin.list.save nodesource.list nodesource.list.save noobslab-ubuntu-macbuntu-xenial.list noobslab-ubuntu-macbuntu-xenial.list.save notepadqq-team-ubuntu-notepadqq-xenial.list notepadqq-team-ubuntu-notepadqq-xenial.list.save runescape.list runescape.list.save saiarcot895-ubuntu-myppa-xenial.list saiarcot895-ubuntu-myppa-xenial.list.save spotify.list spotify.list.save trinity.list trinity.list.save ubuntu-elisp-ubuntu-ppa-xenial.list ubuntu-elisp-ubuntu-ppa-xenial.list.save unity8-desktop-session-team-ubuntu-unity8-preview-lxc-xenial.list wine-ubuntu-wine-builds-xenial.list wine-ubuntu-wine-builds-xenial.list.save
If relevant, and you can't tell by the previous bits of information I provided, I am operating on Ubuntu 16.04.1.

sudo apt update
after. Seems obvious, but I forgot to do this -
