Dear list, since a couple of years I am a happy user of syncevolution under Debian testing + Synthesis SyncML on my Android device (I only use it for the addressbook). However now, when I try to sync, I run as usual syncevo-http-server http://localhost:9000/syncevolution ... but when I start the sync from the device, I get the following error in the terminal: First ERROR encountered: error code from SyncEvolution error parsing config file (local, status 20010): addressbook: backend not supported by any of the backend modules (syncxmlrpc, syncsqlite, syncqtcontacts, syncmaemocal, synckcalextended, syncfile, syncdav, syncakonadi, syncaddressbook, syncactivesync, platformkde) or not correctly configured (backend=addressbook databaseFormat= syncFormat=) The configuration itself hasn't changed in any way except for the DeviceID which I just updated (because for some reason which is a mystery to me - but which I don't think has anything to do with the error I am writing about - my copy of Synthesis was raising an "invalid license" error, and when I reregistered it, it changed DeviceID). Since it has been some weeks since I last synced, I'm not able to recollect exactly which packages I may have upgraded since. Does anybody have any hint of what is going wrong? Are there known problems with recent evolution versions? (I am using 3.8.5) Thanks in advance for any help, Pietro Battiston
