hydrogen problems (beowulf / chimaera)

Hi folks,

i just installed hydrogen on two machines, one running beoulf, the other one running chimaera.
The chimaera installation has (important) rests of a previous installation in local .hydrogen, the one on beowulf was native.

Problem specific to the chimaera install:

crash as soon as the mixer is opened.

Problems to both installations mainly concern filesystem permissions regarding drumkits:



(E) Filesystem::check_permissions Audiophob is not writable
(E) Filesystem::file_copy unable to copy /usr/share/hydrogen/data/drumkits/Audiophob/drumkit.xml to /usr/share/hydrogen/data/drumkits/Audiophob/drumkit.xml.bak, /usr/share/hydrogen/data/drumkits/Audiophob/drumkit.xml.bak is not writable                                                                     
(E) XMLDoc::write Unable to open /usr/share/hydrogen/data/drumkits/Audiophob/drumkit.xml for writing

... and so on for all other drumkits in  /usr/share/hydrogen/data

To me it is asolutely correct that these paths are not writable to unprivileged users !!

Why in hell does hydrogen expect to be allowed to write into folders belonging to the installation ???

Both installations also moan regarding missing midi notes for these drumkits. Where do i find these?  There seems no appropriate package available.

THX

EDIT: the mixer problem appears to be due to an incompatibility with the rests of the old installation (as far as i remember, it could have been 0.96 or even older). Which looks like a bug in hydrogen itself and not an issue with the packaging.

Re: hydrogen problems (beowulf / chimaera)

Although I've never seen that error, I wonder if these are installed
I haven't run this program for some time... so I've left in the versions in the list.

libportaudio2_19.6.0-1_amd64.deb libportsmf0_0.1~svn20101010-5_amd64.deb 
libportmidi0_217-6_amd64.deb hydrogen-data_0.9.7-6_all.deb 
hydrogen-doc_0.9.7-6_all.deb 
hydrogen-drumkits-effects_2017.09.19~dfsg-1_all.deb 
hydrogen-drumkits_2017.09.19~dfsg-1_all.deb 
hydrogen_0.9.7-6_amd64.deb

I usually install fluid synth and timidity and use sound fonts too.

hope this helps.

Re: hydrogen problems (beowulf / chimaera)

These packages were all installed. I installed the midi apps and soundfonts. This did not remove the warning on missing soundfonts, but starting the mixer will not crash hydrogen anymore. For whatever reason. If i happen have a free moment, i'll check how to setup the midi stuff with hydrogen.

(But first of all i need to deal with the bad news that i will lose my home temporarily for about 1-2 months due to a larger water damage in the building of my appartment. )
