musescore_2.0b-1_amd64.deb won't install in ubuntu 14-04

• Nov 3, 2014 - 13:37

I downloaded musescore_2.0b-1_amd64.deb a few weeks ago and tried to install it with gdebi installer.
However in won't install with the error:
Dependency is not satisfiable: libqt5core5a(>=5.3.0).
However, the latest version in ubuntu trusty is 5.2.1 and apt-get install libqt5core5a gives:
"libqt5core5a is already the latest version".
If version 5.3.0 is required, please provide it in the package. ubuntu trusty tar is an LTS distribution and I can not upgrade to later less stable versions.
Please advice.

Thanks for your reply that clarifies a lot. However, as I wrote I don't want to upgrade to 14.10 as I stick since 2006 to the LTS distributions ( after having problems with the intermediate ones). I have to install it on several systems and many users are well, not complete computer illiterates but not accustomed to changes (they are former windows users) but not accustomed to a yearly overhaul of there system.
Do you know if it's possible to install QT 5.3 in 14.04. The other option I have of course is to run 14.10 in a virtual environment and there do the testing.
Looking forward to your reply,

I'm pretty sure it can be done. You don't need a whole new ubuntu to install a particular program so long as you can get to the code for it. I run xubuntu 12.04 64-bit AMD and have installed Qt 5.3.2. Even then, though, I couldn't get the MuseScore Linux Nightlies to run. I built 2.0 Beta 1 from source and it runs fine, though.

I can't remember the exact steps as I basically just googled it, copied some command-line stuff and pasted it in a terminal. It involves adding a PPA (LP-PPA-ubuntu-sdk-team/precise in my case) to your repository list, installing Qt, making sure your $PATH points to Qt and then following instructions on this forum for building MuseScore from source.

I suspect that I went to the Qt site ( and found the answer to the first part in the wiki there.

Yes ! See…

I «enjoy» Qt-5.3.1 in my Mint17 (=Ubuntu 14.04)

This installation is a first step, and you have to tell explicitly where it lays.

For that I have a ~/.bashrc file with the following line

An I have a ~/musescore/lancemscore which reads

export QT_PLUGIN_PATH=/home/leleu/Qt5/5.3/gcc_64/plugins/
export LD_LIBRARY_PATH=/home/leleu/Qt5/5.3/gcc_64/lib/
cd /home/leleu/musescore/MuseScore/build.release/mscore/

/home/leleu/musescore/MuseScore/build.release/ being the repertoryof the available mscore binary
