I tried editing /etc/apt/sources.list
$ diff sources.list-bak0 sources.list 38d37 < 57a57,58 > > deb [ allow-insecure=yes ] http://ppa.launchpad.net/mythbuntu/30.0/ubuntu cosmic InRelease
from https://launchpad.net/~mythbuntu/+archive/ubuntu/30.0 "This PPA does not contain any packages yet" UGH!!!
I restored sources.list
$ sudo add-apt-repository ppa:mythbuntu/30

that looks like it worked
sudo apt-get install mythtv
a screen appeared titled "configuring mythtv-database" and asked "will other computers run MythTV?" I answered NO
Configure
bring over old files
from my old home directory:
$ ls -a .mythtv/ 3rdParty Cache-mythfilldatabase-myth-bob Cache-mythtv-setup-myth-bob config.xml lircrc MythGallery MythVideo RAOPKey.rsa themecache thumbcache backuprc Cache-mythfrontend-myth-bob channels HardwareProfile MythBrowser MythMusic pytmdb3.cache remotecache themes tmp $ cp -pr .mythtv ~/.
for the purpose of testing my setup without damaging my existing recordings, I will not mount my 2TB storage disk. Instead, I'll just create the /storage directory locally:
$ sudo mkdir /storage $ sudo chmod a+rwx /storage
the mythtv group
I needed to add my user to the mythtv group - https://help.ubuntu.com/community/MythTV/Install/mythtv-group
$ sudo usermod -a -G mythtv USERNAME
I tried to run the Mythtv Backend setup again, but it still complained that I was not a member of the mythtv group: "You must be a member of the mythtv group before starting any mythtv applications. Would you like to automatically be added to the group? (Note: sudo access required)". I answered "No" because I'm trying to do it, myself.
I checked:
$ groups ME ME : ME adm cdrom sudo dip plugdev lpadmin sambashare mythtv $ id uid=1000(ME) gid=1000(ME) groups=1000(ME),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),120(lpadmin),128(sambashare)
maybe I need to log out and back in? I'll just reboot...
it worked, now I get
$ groups ME ME : ME adm cdrom sudo dip plugdev lpadmin sambashare mythtv $ id uid=1000(ME gid=1000(ME) groups=1000(ME),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),120(lpadmin),128(sambashare),132(mythtv)
backend setup reported that it could not connect to the database. Somehow, it had the wrong password. I had to look in config.xml to find out the password to enter. Then, the backend setup GUI launched. I exited that because I want to try and restore from my old mythconverg database
restore old database
I listed my old files:
$ ls -Ftl --full-time recordings/mythcon* -rw-r--r-- 1 root root 66899483 2019-01-18 22:41:57.622909353 -0800 recordings/mythconverg-1317-20190118224125.sql.gz -rw-r--r-- 1 root root 74812011 2019-01-09 15:51:11.349710585 -0800 recordings/mythconverg-1317-20190109155034.sql.gz -rw-r--r-- 1 root root 74614069 2018-08-18 08:32:26.389590246 -0700 recordings/mythconverg-1317-20180818083158.sql.gz -rw-r--r-- 1 root root 72127370 2018-08-11 08:06:00.198474597 -0700 recordings/mythconverg-1317-20180811080525.sql.gz -rw-r--r-- 1 root root 69849291 2018-08-04 13:18:37.706524133 -0700 recordings/mythconverg-1317-20180804131804.sql.gz -rw-rw-rw- 1 root root 17933724 2011-05-28 07:47:48.678225587 -0700 recordings/mythconverg-148-11.sql.gz
using instructions at Database_Backup_and_Restore, I restored from the 9 Jan backup:
$ /usr/share/mythtv/mythconverg_restore.pl --drop_database --create_database --directory=/media/troy/d70970b0-e22c-47ae-a9e0-5d9c637aa073/mythtv/recordings/ --filename=mythconverg-1317-20190109155034.sql.gz --verbose .... Restored 4194 of 4194 lines. Successfully restored backup. Found DBSchemaVer: 1317. Setting database character set.
now, let's run the backup setup GUI, again, to see if it looks like it really did it...
settings for the backend
It looks to me like this worked and my old settings are recovered. Now, I need to
- copy a few old recordings over to the new directory for testing
- check all the entries in the backend settings GUI
- verify that mythfilldatabase doesn't fail
- try out the frontend
Live TV
I made an attempt at using the frontend to watch Live TV, but it didn't work. I checked /var/log/mythtv/mythfrontend.log and found this:
Feb 9 17:54:36 PVR-Bob mythfrontend.real: mythfrontend[21812]: E CoreContext livetvchain.cpp:293 (GetEntryAt) It appears that your backend may be misconfigured. Check your backend logs to determine whether your inputs, lineups, channels, or storage configuration are reporting errors. This issue is commonly caused by failing to complete all setup steps properly. You may wish to review the documentation for mythtv-setup.
I checked the log from mythtv-backend: /var/log/mythtv/mythbackend.log
Feb 9 17:54:36 PVR-Bob mythbackend: mythbackend[21759]: E TVRecEvent threadedfilewriter.cpp:126 (Open) TFW(/storage/mythtv/livetv/1002_20190210015436.ts:-1): Opening file '/storage/mythtv/livetv/1002_20190210015436.ts'.#012#011#011#011eno: Permission denied (13)
I tried an experiment:
$ sudo -i -u mythtv $ cd /storage $ cd mythtv $ cd livetv $ touch foo touch: cannot touch 'foo': Permission denied
maybe I just simply have a file permissions problem!
$ sudo -i -u mythtv
$ bash
mythtv@PVR-Bob:/storage$ mkdir -p mythtv/{banners,coverart,db_backups,fanart,livetv,music,musicart,pictures,posters,recordings,screenshots,trailers,videos}
making the directories as user 'mythtv' seems to have resolved that problem
testing Frontend
I copied some files from my hard drive of recordings:
$ sudo cp -v -pr /media/troy/d70970b0-e22c-47ae-a9e0-5d9c637aa073/mythtv/recordings/*_20180{8,6}*mpg .
$ sudo cp -v -pr /media/troy/d70970b0-e22c-47ae-a9e0-5d9c637aa073/mythtv/recordings/*_20180511*mpg /storage/mythtv/recordings/.
/storage/mythtv/recordings$ sudo chown mythtv:mythtv *
/storage/mythtv/recordings$ sudo chmod a+rw *
I've been able to watch Live TV, record Live TV, record a program from the Program Guide, and watch recorded shows
The problem is that the video isn't smooth :(
