dependencies issue on Ubuntu Bionic

[jonadem]

I tried to install the software but I was blocked very soon, I get a dependencies conflict.

The problematic package is librtmidi-dev on Ubuntu 18.04 "Bionic".

When I try to install it, I get :

jona@jona-ThinkPad-T520:~/Softwares/linthesia$ sudo apt install librtmidi-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 librtmidi-dev : Depends: librtaudio-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

My guess is that the issue lies in this chain : librtmidi-dev -> libjack-dev -> libjack0 >< jackd1 <- lmms
lmms is installed from the official repository (a lot of other softwares are depending on jackd1 AFAICT).
I also tried to install librtmidi-dev:i386 but I get the same problem.

Can someone give me an hint ?

Thank you

what do you get when you try to install alone librtaudio-dev ?

If I try to install librtaudio-dev, I get :

jona@jona-ThinkPad-T520:~$ sudo apt install librtaudio-dev

I think you can try to type "yes" and then install librtmidi-dev , looking to the output it seems nothing harmful will be removed

[jonadem]

I don't want lmms to be removed. This is an end-user application and I want to keep it. On top of that, I have a clean apt autoremove if I don't install librtmidi-dev.

[allan-simon]

@jonadem , was this issue solved with a recent upgrade of ubuntu ?

[jonadem]

Yes, I was able to install both lmms and linthesia on Ubuntu 19.10 (Eoan Ermine). As a side note, I started with linthesia.
