I recently managed to get ASL to work on a Raspberry Pi 3 using the Allstarlink ASL_1.01-20180228-armhf-raspbian-stretch-image. I wanted a radio-less setup and use a DVSwitch IAX client for ASL and a DMR radio to my talkgroup. Then I configured and got ASL to DMR working perfectly. Today I did and apt-get update and apt-get upgrade. The result was that Asterisk stopped working. Last few linkes of asterisk startup are: -- rpt (Rx) initiating call to USRP/127.0.0.1 on usrp/127.0.0.1:34001 [Feb 4 07:48:35] WARNING[861]: chan_dahdi.c:928 dahdi_open: Unable to open '/dev/dahdi/pseudo': No such file or directory [Feb 4 07:48:35] ERROR[861]: chan_dahdi.c:7906 chandup: Unable to dup channel: No such file or directory rpt:Sorry unable to obtain pseudo channel [Feb 4 07:48:35] WARNING[862]: chan_dahdi.c:928 dahdi_open: Unable to open '/dev/dahdi/pseudo': No such file or directory [Feb 4 07:48:35] ERROR[862]: chan_dahdi.c:7906 chandup: Unable to dup channel: No such file or directory rpt:Sorry unable to obtain Rx channel [Feb 4 07:48:37] ERROR[828]: app_rpt.c:22223 rpt_master: Continual RPT thread restarts, killing Asterisk Is there a way to get this back to how it was so I don't have to do a total wipe and start from scratch again? Right now it looks to me as if I get a node running I can't ever upgrade anything. Thanks in advance. Guillermo - HK4KM
