This might appear as a really stupid question, but I can't figure it out myself.

I cannot install Carla on Ubuntu 18.04 LTS (64 bit). They offer 3 ways to install Carla, and none is working yet for me.

  1. Pressing Debian/Ubuntu on their downloadpage reports:

    could not find carla-git.

    BTW: kxstudio repo is installed.

  2. Precompiled binary reports an error after chmod +x Carla && chmod +x CarlaConfig :

    $ ./Carla
Carla: loadlocale.c:130: _nl_intern_locale_data:
  Assertion `cnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' failed.
Aborted (core dumped)

  3. Building from source is installable. But when I try to open it, nothing appears.

I should maybe stick to one solution, but I'm really confused right now which path to take.

Edit 2: I just did a new clean installation of the kxstudio repo. Here is my output of (extracted the relevant part)

sudo apt update


Hit:1 http://ppa.launchpad.net/kxstudio-debian/ubuntus/ubuntu bionic InRelease

then trying to install carla:

sudo apt install carla-git
Reading package lists... Done

    sudo apt install carla-git throws: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package carla-git I ran all the instructions to install the kxstudio repos. Here is a screenshot of my Software & Updates imgur.com/a/sZDR3CE . So the problem seems kxstudio repo not be installed properly?

    @stumblebee I'm sure nobody was offended and you're quite right that this isn't the answer for 18.04 and so not really an answer for this question. You might have explained in your comment, but it's my bad

I have successfully installed Carla on Ubuntu 18.04. Here's how to do it:

  1. go to http://kxstudio.linuxaudio.org/Repositories and install the kxstudio-repos.deb package. You need KXStudio repository for Carla.
  2. NOW you can go to http://kxstudio.linuxaudio.org/Applications:Carla and click on the Debian/Ubuntu (via KXStudio repositories) link to install Carla.

I have run into issues with the kxstudio repository in the past, especially with the bundled version of Carla. Therefore I now download the latest version of the actual release files from their Github repository here:

https://github.com/falkTX/Carla/releases

I find that the latest release at the time I am writing this (Carla_2.0-RC2-linux64.tar.xz) is working very well on both standard Ubuntu 18.04, as well as Ubuntu Studio 18.04. Furthermore, I use it successfully to load Windows-based VST files with the standard version of Wine that comes with 18.04 (wine-3.0).

To prove my version of Ubuntu:

 $ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.1 LTS"

And here is the output of "./Carla" if I start it on the commandline:

$ ./Carla
