An easy workaround was to add "ExecStartPre=/bin/sleep 15" line into my /lib/systemd/system/mythtv-backend.service file:
[Service] User=mythtv EnvironmentFile=-/etc/mythtv/additional.args ExecStartPre=/bin/sleep 15 ExecStart=/usr/bin/mythbackend --quiet --syslog local7 $ADDITIONAL_ARGS StartLimitBurst=10 StartLimitInterval=10m Restart=on-failure RestartSec=1 -- You received this bug notification because you are a member of UBUNTU - AL - BR, which is subscribed to Mythbuntu. https://bugs.launchpad.net/bugs/1615197 Title: "all tuners are currently busy" and mythweb not working properly Status in Mythbuntu: New Bug description: I did a fresh install of Mythbuntu 16.04. I have 3 identical Hauppauge Nova TD dual USB DVB-T tuners that use the DiBcom 7000PC driver. After a reboot if I try to watch live TV I get a message "All tuners are currently busy". In addition to "all tuners are currently busy" my mythweb has all the headers in place but the Listings page has no content and says: "Warning at /usr/share/mythtv/mythweb/modules/_shared/tmpl/default/header.php, line 12: !!NoTrans: Cannot modify header information - headers already sent by (output started at /usr/share/mythtv/mythweb/modules/_shared/tmpl/default/header.php:152)!!" After a backend restart 'sudo /etc/init.d/mythtv-backend restart' everything works. This is possibly related to tuners not being ready before mythbackend starts up. There are a few possible workarounds, but I haven't picked one simple enough yet.
