Code: Select all

sudo apt-get purge kxstudio-repos kxstudio-repos-gcc5

then re-add the kxstudio repos again.

I purged the old kxstudio repo configs, then re-added them. This did not make any difference. My installation of jack2 is 6:1.9.10~git20140122-1+kxstudio~raring1. For jack1 I have the following version available: 2:0.124.2~20150719-1~wiley3, but when I try to install it I get the following message:
Could not mark all packages for installation or upgrade
jackd1:
Depends: libjack0 (2:0.124.2~20150719-1~wiley3) but 6:1.9.10~git20140122-1+kxstudio~raring1 is to be installed.

Do you have any other advice?

falkTX wrote:yes, keep forcing the install until it lets you do that.
ie, do 'sudo apt-get install jackd2' and if it fails add the complained package to the end of the command, like:
sudo apt-get install jackd2 libjack-jackd2-0
keep going until you it either forces the install or gives a final unrecoverable error.
I suspect it will let you install. if not, paste here the final error.

I already have jack2 installed. I am assuming that you meant to say I should force the install of jack1?

falkTX wrote:no, that was on purpose. the version you have of jack2 is older.
but forcing jack1 install might be good too, that way test if updates are really working.

I am also curious as to why when I try to re-install jack2d I am being told it is already the latest version, when it is from raring. Do you know what would cause that?

falkTX wrote:the jack2 wily version doesn't build right now.

btw, did you enable the gcc5 variant of the repos?
it's needed for ubuntu >= 15.04

I don't really know how you got the jack1 version as 6:1.9.10~git20140122-1+kxstudio1~raring1.
I stopped overriding the jack version to jack2 on 12.04.

this might be a bit tricky to solve, but the solution will for sure be to install jack1 first.

perhaps this?

Code: Select all

sudo apt-get install jackd1=2:0.124.2~20150719-1~wily3 libjack0=2:0.124.2~20150719-1~wily3

Success! QTractor now starts... One quick question. Should I uninstall jack2 or leave both it and jack1 installed. Will having both cause a conflict? When I use Cadence to automatically connect to jack will it automatically sort things out?

falkTX wrote:it should not be possible to have both installed.
but errm, if things are working now leave them until you need to change something.

A HUGE thank you for all of your expert help in getting this issue resolved! A quick note in case this comes up again - instead of leaving both jack1 and jack2 installed, I went ahead and uninstalled jack2. Everything appears to be working normally...
