Error "[Errno 8] Exec format error"

[hedderz]

Hi All

I have just installed SABnzbd on my nas (recently factory defaulted) and every download that it completes a download, I get the error in the subject Error "[Errno 8] Exec format error" Error "[Errno 8] Exec format error. I am very new to linux so can handle the basics but will need quite a bit of hand holding. Does anyone have any ideas what could be the issue.

NAS: Netgrear ReadyNAS NVX v4.2.30
SABnzbd: 1.2.0 (upgraded from 1.1.1)
Python: 2.7.10

Thanks

Hedderz

Error "[Errno 8] Exec format error. 

Did you Google that?

[hedderz]

I did google the error but all the posts seem to regarding custom scripts that people have written and none seem to reference SAB. As I mentioned, I have very new to linux so a lot of what is discussed in the posts go over my head. One post that does mention SAB also includes Sickbeard and a SAB to Sickbeard script but I am not using sickbeard. I am using SickRage however. I am not sure how similar the two are and I also thought that the error was before SickRage got involved as it seems to me, the very uninitiated, the download/extraction is where it is failing and not the renaming/moving if the file.

another post that I found (from this board but in dutch seems to suggest it could be an issue with Unrar. I don't think this is the case with me as when I run the command "apt-get install unrar" I get the following output which seem to suggest unrar is installed and working.
# apt-get install unrar
Reading package lists... Done
Building dependency tree... Done
unrar is already the newest version.

Yes, shell scripts in general. I expect a post-processing script, maybe related to SickRage.

You could post your sabnzbd.log here to show the context where this is happening.

[hedderz]

Sorry for the delay, work has been a bit manic.

Here is the content of my sabnzbd.log. I just tried a reinstall and that didn't work

"Problematic UNRAR" ... I don't know why SAB says, but there must be a reason. And it could be the cause. So let's look at the source code:

Code: Select all

    if not (sabnzbd.WIN32 or sabnzbd.DARWIN):
        version, original = unrar_check(sabnzbd.newsunpack.RAR_COMMAND)
        sabnzbd.newsunpack.RAR_PROBLEM = not original or version < 380
        sabnzbd.newsunpack.RAR_VERSION = version
        logging.debug('UNRAR binary version %.2f', (float(version) / 100))
        if sabnzbd.newsunpack.RAR_PROBLEM:
            logging.info('Problematic UNRAR')

So it's about version. Can you set your SABnzbd log level to +Debug, restart SABnzbd, and find the line 'UNRAR binary version' and post it here?

And post the output of

Code: Select all

rar | head -5

and

Code: Select all

unrar | head -5

here in this thread.

You should update your unrar to unrar-nonfree, not the free one that comes with some OS'es.
Is that possible?

[hedderz]

Here is the UNRAR version

Code: Select all

2017-02-19 16:55:53,329::DEBUG::[newsunpack:149] UNRAR binary version 0.00

When ever I follow the various guides to install the nonfree version I get the following message

Code: Select all

I ran the following, not sure if that helps at all.

Code: Select all

rar | head -5
-bash: /usr/local/bin/rar: cannot execute binary file

Given its location in /usr/local/ that file is not part of a standard debian package, but installed manually (and probably not even compiled for the correct hardware architecture). Remove it.

[hedderz]

OK, I may need a little help to remove it

I tried "apt-get remove rar" but got the following

Code: Select all

apt-get remove rar
Reading package lists... Done
Building dependency tree... Done
Package rar is not installed, so not removed

I am still learning linux so my apologies if this is a very basic question.

[sander]

Code: Select all

mv /usr/local/bin/rar /usr/local/bin/rar.old

Afterwards:

Code: Select all

rar | head -5

... and post the output here.

[hedderz]

rar | head -5
-bash: rar: command not found

[sander]

rar | head -5
-bash: rar: command not found

Good: the bad rar (or: some file pretending to be rar) is gone.
