it happened to me and find the reason now.. but i upgraded from debian 6 to 7 and later to 8 then to 10..
well this is a bug that already has solution and is important! as i pointed i upgrade to debian 10; and in debian 6 works perfectly .. and in this particular bug 971385 reporter saids that debian 9 works.. (that's the reason of Debian 10 sh**t many other packages already have problems) Markus you mail me that "help providing patch" but later i said "read the mails" .. and you said "i cannot be". . also it points that trying to recompile the package it does not integrate to default cos the COMPLICATED sys-v init crips and also the changes not property documented in the changelog respect the upstream.. README.Debian files only has minimal information and tutorial of well documented package does not works Lenz McKAY Gerardo (PICCORO) http://qgqlochekone.blogspot.com
