Trouble scanning channels

[m1tch]

Hey,  I'm using the Linux version. When I try to scan channels it never scans. I tried using w_scan and get several channels. I've looked at logs and can't tell what is failing. Help!!   Thank you.

Here are some of the scanned channels fro w_scan

Which version of Linux are you running, this one isn't using the deb installer and it not configured properly.

Hey Martin.

I did use the deb installer, but I can't say it was configured properly. I followed the installation help from Hauppauge.

Linux robert-VM1 5.8.0-492104061620-generic #1+mediatree+hauppauge~hwe-Ubuntu SMP Fri Apr 16 14:14:47 UTC 20 x86_64 x86_64 x86_64 GNU/Linux

Ok my mistake, I just read the first line, what you probably did is install as root rather then sudo, root doesn't have a home directory and NextPVR needs a user home to install. You can move the recordings folder but do that later.

So as a sudo user run

sudo rm -rf /var/opt/nextpvcr

and then reinstall as shown on the instructions

sudo apt install ./nextpvr-helper.deb --install-recommends

Martin,
I'm still getting the same result.

Sorry I don't support snippets zipped logs only. Testing outside of NextPVR is not supported either, different libraries are known to crash.

Martin,
I forgot to send the logs. Since then I reinstalled UbuntuStudio-20.04.02.0 and reinstalled the hauppauge ppa and tried to get the modules to load. I'm still trying to get it to boot without going to grub-repair. After reinstalling nextpvr using the nextpvr-helper.deb script I am getting the channel list as it should. Thank you for the help you provide.

In case you didn't know this with dualHD you don't need install Hauppauge PPA it all ready build-in to linux kernel the must you may need todo in update the firmware and reboot

[m1tch]

Thanks, but I just finished adding the Hauppauge PPA . It's working now.

I found that the PPA won't work with WinTV QuadHD USB on Ubuntu Studio. It uses non HWE version of the Ubuntu kernel and isn't updated as often. It does work with Hauppauge WinTV-HVR-1265 before adding PPA and WinTV-quadHD pci after the update.

I should have specified that I'm using Ubuntu Studio 20-04.02
