Bug Description

Binary package hint: mythtv-backend

I'm running Hardy Heron Alpha 3, and earlier today, after upgrading several packages including some MythTV packages, I started having this problem.

mythbackend starts up and runs fine, until I try to connect to it via mythfrontend.

Steps to reproduce:
1.) Start mythbackend with: sudo /etc/init.d/mythtv-backend start
2.) Start mythfrontend. At this point backend is still up and running.
3.) Go to "Media Library"->"Watch Recordings".
4.) As soon as I hit "Watch Recordings", mythbackend crashes with:
select(18, [10 11 17], [], [], {19, 249816}2008-01-22 05:27:17.284 MainServer::HandleAnnounce Monitor
2008-01-22 05:27:17.284 adding: mythbox as a client (events: 1)
/usr/bin/mythbackend: symbol lookup error: /usr/bin/mythbackend: undefined symbol: stat64
) = ? ERESTARTNOHAND (To be restarted)

This reproduces every time, with 100% reliability, on my machine.

Let me know if you need me to provide other information.

Thanks!

I have the same problem with k3b on 64bit Hardy:
k3b: symbol lookup error: /usr/lib/libk3b.so.3: undefined symbol: stat64

Howto reproduce: Initially I had to start k3b, select VideoDVD project and try to add files to reproduce the crash.
Right now it crashes immediately after start.

Noticed this today, worked fine one month ago (I believe I used it later as well, but I'm not 100% sure)

Could you take a look at your dpkg.log and see what else got upgraded at the same time?

Ok, how do I get that version?

I'm currently at 0.20.2+fixes15513-0ubuntu3.

I tried running update-manager, and it doesn't show any updates for mythtv.

I tried:
mjb@mythbox:~$ sudo apt-get install mythtv=0.20.2+fixes15513-0ubuntu4
and got:
[sudo] password for mjb:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Version '0.20.2+fixes15513-0ubuntu4' for 'mythtv' was not found

Any clues on how to upgrade to the fixed version??

Thanks!

Ok, I found this page:
https://launchpad.net/ubuntu/hardy/+source/mythtv/0.20.2+fixes15513-0ubuntu4

And I saw that it was marked as "Pending" till about 5 minutes ago, and now it's "Published", but running update-manager and clicking "Check" still doesn't pick up this version.

Sorry if I'm a little clueless, I'm just trying to better understand how the system works.

The mirrors aren't immediately updated. If you are using Synaptic, click Settings, Repositories. Then set "Download from:" to "Main server". click close, then Reload. The updates should now be available. I updated mine and now have no problem.

Yeah, when I woke up this morning, I tried again and got the update. Thanks for the pointer on the ability to change which repository you point to. Could be useful in the future.
