Nothing in MLB TV, either, but it's all star game time, so I'm betting that's correct.
Channels running on current Ubuntu with current updates, Version 2021.05.26.1807
Rescanning TV Everywhere source for Fubo seems to work, but only ~65 channels are returned, the set all above channel ID 6700. I just checked NASA and it's working.
Clicking "rescan" on 6010 Comedy Central returns:
chrome failed to start: [0713/182953.895801:WARNING:resource_bundle.cc(419)] locale_file_path.empty() for locale [0713/182954.169178:FATAL:zygote_host_impl_linux.cc(191)] Check failed: ReceiveFixedMessage(fds, kZygoteBootMessage, sizeof(kZygoteBootMessage), &boot_pid). #0 0x7fc7f5e436e9 (/home/marc/channels-dvr/data/chromedp-chroot/headless-shell/headless-shell+0x2dba6e8) #1 0x7fc7f5dc64a3 (/home/marc/channels-dvr/data/chromedp-chroot/headless-shell/headless-shell+0x2d3d4a2) #2 0x7fc7f5dd3296 (/home/marc/channels-dvr/data/chromedp-chroot/headless-shell/headless-shell+0x2d4a295) #3 0x7fc7f5dd3dde (/home/marc/channels-dvr/data/chromedp-chroot/headless-shell/headless-shell+0x2d4addd) #4 0x7fc7f4d9e9c4
plus lots more.
I've restarted both the DVR and the client with no effect.
My login to Fubo is good, I can view the channels on the Fubo Android TV app on the same device as the Channels client.
