MythTV Official Community Forum

bill6502, thanks for taking the time to look into this. I know it's not explicitly a MythTV problem, but the problems I had getting to this point could be related to depends (referring mostly to the mysql/mariadb issues, not sure about video yet.) Let me summarize where I started. Last July or so, I...

This is very frustrating. No idea how to fix this. At this point it's not a MythTV problem specifically, because other programs also crash playing video, that worked fine before. mpv crashes, I think it uses hardware acceleration. vlc crashes, even when I disable acceleration. chrome works for strea...

OK, it's got to be related to video, drivers or codecs or something. Both VLC and MPV crash when trying to play a video that worked fine before the upgrade. mpv says: [ffmpeg] AVHWDeviceContext: Failed to query surface attributes: 20 (the requested function is not implemented). [vo/gpu/vaapi-egl] fa...

As of this morning, I see the system is starting up on schedule, recording, and shutting down afterward. So I'm not missing any recordings, I just can't watch them until I fix mythfrontend.

Yes, MySQL 8.0 can be installed in *buntu 19.10. I did it. Seemed to "hang" for about 5 minutes at 86 percent, but eventually finished. Without explicitly installing MySQL 8 first, upgrade to 20.04 still wants to replace mysql with mariadb and uninstall mythtv. I got everything working on 19.10 + My...

So the reason I had held the mysql package was to see if that would prevent the upgrade from 19.4 to 19.10 from replacing mysql with mariadb. But we wanted to watch something before I could run the upgrade and I forgot it was held when I initially ran dpkg to get the output. So now I've just upgrade...

I wasn't holding any package when I tried upgrading, any time. I only held that yesterday but never tried upgrading while it was held. I have to upgrade to 19.10 first, before 20.04. And when I start upgrading to 19.10 and look at details before clicking start, it wants to uninstall mysql 5.7 and in...

Oh! I forgot I had added a hold on mysql 5.7 before I ran that. (Added after the problems described earlier.) I've since removed the hold, and it shows ii instead of hi... sudo dpkg -l *mysql-server* *mariadb-server* Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/hal...

I can run dpkg tomorrow if you need the output. But I know it's mysql 5.7, and no mariadb.

Current state: I upgraded MythTV to 31. Checked everything out, works, made a backup. Ran another update, let it update everything for 19.04. Checked it out and made a backup. Next problem: To upgrade OS to 20.04, I have to upgrade to 19.10 first, right? When I begin the upgrade to 19.10 and look at...

Timeshift restore worked. I'm back on Xubuntu 19.03 / MythTV 30. I watched a few videos on Timeshift restores, and saw that once you start the restore, it drops to a console, then automatically reboots when finished. That wasn't clear from documentation/descriptions I'd seen, so I was worried the re...

I will check that tomorrow. Giving up for the night before I make more of a mess.

One question: Anybody familiar with Timeshift? Can it restore a snapshot from an earlier version of the OS? I have a snapshot from today, just before I started upgrading. What happens to files in use?

Ugh. The database dies after a while. Guess I'll be missing some recordings.

After rebooting, I see MariaDB is running. (Checked the welcome message. Not MySQL anymore) But mythbackend is not running. If I run sudo systemctl restart mythtv-backend.service It starts the backend (after about 5 minutes) but has "broken" MariaDB (can't connect.) So I reboot again, and this time ...
