That processor should be fine. It may not be able to do mythcommflag<br>
in real time, but it certainly will be able to record properly. My<br>
mother's MythTV box is running Mythbuntu 16.04 on an ancient AMD<br>
Athlon II X2 245 2.9 GHz dual core processor and that is fine. What<br>
may not be fine is that MythTV uses rather more RAM now. My mother's<br>
box only has 4 Gibytes of RAM, and while that does work, it swaps when<br>
she needs to use Thunderbird or Firefox. Having less than 4 Gibytes<br>
of RAM might be a problem.<br>
<br>
But you really do need to change to using the 64-bit version. As of<br>
18.04, Ubuntu no longer supports the i386 version, and for a number of<br>
versions before that the support has not been good - the i386 versions<br>
tend to have problems. And MythTV has not been tested much on i386<br>
versions for a long time.<br>
<br>
To change to a 64-bit version, this should work:<br>
<br>
1) Install gparted. Use it to shrink down your EXT4 partition so you<br>
have enough room to create a new partition to hold your existing<br>
recordings (and anything else you want to save).<br>
<br>
2) Create a JFS or XFS partition in the spare space. To use JFS, you<br>
may need to install the jfsutils package. Add it to fstab and mount<br>
it. I call my recording partitions "rec1", "rec2", and give them<br>
labels so that I can use the LABEL= format in fstab. I find that much<br>
saner to use than UUIDs. I mount the partitions under /mnt, using the<br>
same name for the mountpoint as the partition label:<br>
<br>
/mnt/rec1<br>
<br>
Make sure the mount point is accessible to MythTV.<br>
<br>
3) Create a subdirectory for storing your recordings on the new<br>
partition. I use "recordings". Make sure the subdirectory is<br>
accessible to MythTV (making it mythtv group should do that, but I<br>
just make mine universally accessible).<br>
<br>
4) Use mythtv-setup to add the new subdirectory (eg<br>
/mnt/rec1/recordings) to the Default storagegroup.<br>
<br>
5) Move all the recording files to the new partition:<br>
<br>
mv -v /var/lib/mythtv/recordings /mnt/rec1/recordings<br>
<br>
6) Run mythfrontend and check that the recordings are still accessible<br>
from there.<br>
<br>
7) Copy anything else you want to save from the existing system<br>
partition across to the new partition.<br>
<br>
8) Shut down mythbackend and then use<br>
/usr/share/mythtv/<a href="http://mythconverg_backup.pl" rel="noreferrer" target="_blank">mythconverg_backup.pl</a> to create a database backup on<br>
the new partition.<br>
<br>
9) At this point your system partition should be quite empty and you<br>
might like to use clonezilla to do an image backup of it to the new<br>
partition (or somewhere else - clonezilla can back up things over your<br>
network to other boxes). I would think the backup would likely be<br>
only 10 Gibytes or so, if you use bzip compression.<br>
<br>
10) Boot from your 64-bit Mythbuntu install media and tell it to<br>
install over the top of the existing EXT4 system partition, rather<br>
than using the default option to format and use the whole disk. You<br>
might want to tell it to use only a small size for the system<br>
partition, say 50 or 100 Gibytes. That will leave a gap between the<br>
system partition and the new recordings partition. You can later use<br>
gparted to move the bottom end of the recordings partition down so<br>
that the extra space is added to it.<br>
<br>
11) Reboot into your new 64-bit Mythbuntu. Do a full "apt update" and<br>
"apt upgrade". Reboot.<br>
<br>
12) Add the MythTV PPA and update to the latest version of MythTV that<br>
is available.<br>
<br>
13) Copy back everything you stored on the other partition.<br>
<br>
14) Shut down mythbackend. Use<br>
/usr/share/mythtv/<a href="http://mythconverg_restore.pl" rel="noreferrer" target="_blank">mythconverg_restore.pl</a> to restore your backup<br>
database. Run mythtv-setup, so that the database schema will update<br>
if it is different from the backed up version. Exit mythtv-setup and<br>
start mythbackend.<br>
<br>
15) Start mythfrontend and check that it is working and can see the<br>
old recordings.<br>
