Ubuntu 17.10 contains libmicrohttpd12 but I also need libmicrohttpd10 for kodi. Can I have both ?

It is available in 16.04, and installing the 16.04 version on 17.10 is likely to work (assuming you really cannot install 16.04; otherwise you should do that). However, do not just download a .deb and install it, because if a vulnerability is found in it, you will not automatically get the fix. Instead, you can add the 16.04 repositories as follows.

First, copy your current sources.list to a new file in /etc/sources.list.d:

sudo cp /etc/apt/sources.list /etc/apt/sources.list.d/xenial_for_libmicrohttpd10.list

The name of the new file is just a reminder for the future you of what its purpose is. You can also add a more elaborate comment in it.

Second, use your text editor of choice to replace all occurrences of artful in the file to xenial. For example:

printf ',s/artful/xenial/\nw\n' | sudo ed /etc/apt/sources.list.d/xenial_for_libmicrohttpd10.list

Finally, just to be sure that no Xenial package other than libmicrohttpd10 will be accidentally installed, give them a low priority by creating a file in /etc/apt/preferences.d like this:

Package: *
Pin: release n=xenial
Pin-Priority: 99

Package: libmicrohttpd10
Pin: release n=xenial
Pin-Priority: 500

Then you can do sudo apt update && sudo apt install libmicrohttpd10.

  • sudo sed -i 's/artful/xenial/' /etc/apt/sources.list.d/xenial_for_libmicrohttpd10.list seems simpler. Also, maybe consider adding only the universe repo. – muru Dec 26 '17 at 08:36
  • @muru I don't like sed -i because it is non-standard (there is a joke: using sed -i is like alcohol-free beer, it tastes the same but you know it ain't right!). Adding only universe could be problematic if a dependency from main is needed (it is not currently the case since all the dependencies are in Artful, but some could be removed further down the line if their sonumber increases). – fkraiem Dec 26 '17 at 08:45
  • It maybe non-standard for POSIX, but it's perfectly fine for GNU, and hence Ubuntu. – muru Dec 26 '17 at 08:46
  • @muru I know that; what is your point? I said why I did not include it in my answer; I never said it does not work. – fkraiem Dec 26 '17 at 10:11
  • That your reason isn't much of a reason, after all, you stopped being POSIX only when you used sudo, so POSIX clearly doesn't matter. – muru Dec 26 '17 at 10:24
  • @muru What you think about my reason (for choosing one particular example) matters how? – fkraiem Dec 26 '17 at 10:27
  • you're the one who asked what my point was, if it didn't matter, don't ask. End of discussion. – muru Dec 26 '17 at 10:48
