All my downloads fail

[Pahkis]

Version: 0.6.4
OS: Ubuntu 10.4
Firewall: no
Is the issue reproducible: yes

So I first installed sabnzbd+ a few months ago and I had no problems at all, I followed the installation guide from ainer.org to the letter and it was just smooth sailing. But now that I set up a new server type of computer, I seem to be having a lot of problems with sabnzdb+. I followed that same guide again and it seemed to be going just fine but now that I download files, they all fail.

When I open the download report from the + button in the home page of sabnzdb it just says that the download failed. No explanation at all.
For example:
Completed at 19:08:40 on Monday 13 June 2011
Download:
Downloaded in 3 seconds at an average of 4.5 MB/s
Category:
tv
Path:
/home/myusername/Downloads/incomplete/filename

In some cases it says that the download size is les then 20MB and then in some cases it's like 50% of the file size and everything between that.

Perhaps I'm missing something here, please bear with me, I'm a newbie when it comes to Ubuntu even tho I have used it for a few months now.

Thanx in advance for some good tips I could try to solve this problem.

Which skin do you use?
Please show a screenshot.

[Pahkis]

My skin is smpl-black (I hope that is what you mean with skin). It seems I can't include a screenshot here, I just get the message that I need to contact the administrator and the file size might be too big even tho it's a really small picture.

[shypike]

Just send it by email to bugs at sabnzbd.org

[Pahkis]

Alrighty, screenshots sent!

Nothing conclusive.
Do you seen warnings about missing par2 or unrar at startup?
You'll have to take a look in the logging file on the Status page.

[Pahkis]

The warnings page itself doesn't have any warnings. Then the log file from the Status page... the log shows lines like
2011-06-12 19:43:03,801::INFO::[newsunpack:781] Par verify failed on /home/...
2011-06-12 19:43:03,802::INFO::[postproc:505] Par2 check finished on file

And it looks like pretty much everything I have tried to download has had the same two lines mentioned above. So it says that it has failed the par verify and then the par2 check finished.

[shypike]

Do you have anything in the box "Extra PAR2 Parameters" in Config->Switches?
Can you check from a shell window which par2 version you have?

[Pahkis]

In the Extra Par2 Parameters box I have t0. I'm not sure how can I check which par2 version I have from a shell window but the name of the download for Par 2 is par2cmdline-0.4-tbb-20090203-lin32. Does that help?

[shypike]

t0 is definitely wrong, because it should be -t0
Mind the minus sign.

[Pahkis]

Well, there we go! Right now I'm seeing very good things happening, like the words "verifying, starting repair, etc." and the best of all, Status: Completed. Thank you so very much man, you know your stuff!!!

[shypike]

SABnzbd tries to detect error messages coming back from par2.
However, as far as par2 is concerned "t0" is a file that it cannot find and cannot reconstruct...
Should you have entered something like -faster, SABnzbd would have warned you in the history details.

[Pahkis]

Alrighty, I will remember that. This have been really enlightening. Thanx again for your help.
