I'm trying to install PIL a python module on ubuntu
I first need to install a package called python-imaging using the following command
sudo apt-get build-dep python-imaging When I try and do this I get the error
E: You must put some 'source' URIs in your sources.list I saw this question whihc shows how to fix via the GUI but I'm using the command line. Does anyone know how I can fix this error..?
UPDATE: Based on the below answers I've updated my package list but I now get this error. Not sure if it is related, if not I'll start a new question as I can't find reference to the error anywhere.
E: Build-Depends dependency for python-imaging cannot be satisfied because candidate version of package python-all-dev can't satisfy version requirements 7 Answers
software-properties-gtk option "Source code"
I recommend this for the desktop:
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>.
I've couldn't find a clean CLI method so I create this bug report for it:
Tested on Ubuntu 16.04 to 18.04.
CLI method
I recommend this for Docker images:
sudo cp /etc/apt/sources.list /etc/apt/sources.list~ 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 successfully 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 Previously mentioned at: go and upvote that answer.
Note however that the /etc/apt/sources.list file contains lines such as:
# deb bionic partner # deb-src bionic partner which means that the above sed would enable sources but not non-sources for some types of repos. I don't think that it matters much though.
You can edit the source list (/etc/apt/sources.list) directly. I think you need to add in/uncomment these lines:
deb-src trusty main restricted #Added by software-properties deb-src trusty restricted main universe multiverse #Added by software-properties deb-src trusty-updates restricted main universe multiverse #Added by software-properties deb-src trusty-backports main restricted universe multiverse #Added by software-properties deb-src trusty-security restricted main universe multiverse #Added by software-properties deb-src trusty-proposed restricted main universe multiverse #Added by software-properties I worked this out by disabling the source code option, and saving one copy of the sources.list file, then enabling the source code option, saving another copy, then running diff on both.
You may want to change the prefix to the prefix of the other sources in your list (so it uses your nearest repo mirror), and you can also ignore the #Added by software-properties.
After editing sources.list, run sudo apt-get update before trying to install again.
The full diff can be found here
Another way is to generate a new one. One method to get a complete sources.list is to use this site:
4Edit /etc/apt/sources.list
sudo nano /etc/apt/sources.list Then remove # or add lines with deb-src $url, for example:
deb saucy main restricted deb-src saucy main restricted Or copy from the existing lines, e.g.
deb blah blah deb-src exact same blah blah Then run:
sudo apt-get update See for additional information.
1Here is the command line solution
cat /etc/apt/sources.list | grep deb-src # see what will get changed typical output of above cmd
# deb-src bionic main restricted # deb-src bionic-updates main restricted # deb-src bionic universe # deb-src bionic-updates universe # deb-src bionic multiverse # deb-src bionic-updates multiverse # deb-src bionic-backports main restricted universe multiverse # deb-src bionic partner # deb-src bionic-security main restricted # deb-src bionic-security universe # deb-src bionic main universe restricted multiverse # deb-src bionic-security multiverse if you are good changing above lines, which is always true on a fresh ubuntu install, then issue :
sudo sed -i~orig -e 's/# deb-src/deb-src/' /etc/apt/sources.list which does a backup of input file, then a search for commented out deb-src where it removes the comment to make those lines active ... following refresh of local metadata will give your machine awareness of new catagories of ubuntu packages
sudo apt-get update now issue once again your original command which failed with :
E: You must put some 'source' URIs in your sources.list For Ubuntu 16.04, I successfully made these updates to sources.list :
$ sudo diff /etc/apt/sources.list /etc/apt/sources.list.bkp 6c6 < deb-src xenial main restricted --- > # deb-src xenial main restricted 19c19 < deb-src xenial universe --- > # deb-src xenial universe 39c9 < deb-src xenial-backports main restricted universe multiverse --- > # deb-src xenial-backports main restricted universe multiverse 53c53 < deb-src xenial-security multiverse --- > # deb-src xenial-security multiverse In Linux Mint (I am on version 18) you can go to Software Sources (search for it in the start menu or open it from a terminal with software-sources). There, on the first tab, you will find a checkbox Enable source code repositories. If you enable this the program will put the correct lines into your /etc/apt/sources.list.d/official-source-repositories.list file. Just don't forget to sudo apt-get update (or hit Update the cache in the Software Sources) after that.
My solution takes the already configured deb lines and adds them as deb-src ones. Tested using the perl:5.28 docker image which builds upon buildpack-deps:buster which builds upon debian:buster:
sudo su - grep '^deb ' /etc/apt/sources.list | perl -pe 's/deb /deb-src /' >> /etc/apt/sources.list
