Unpacking failed, see logfile -- 7zip

Post by hoju3508 »

Hi,

Recently I've been seeing this error message and don't understand why 7zip is in play and there are no 7zip files. NZB file is created using NZBKing.com (ruling out NZBKing.com since 2/3 nzbs from there failed from same site) and I'm using v4.5.5.

Code: Select all

Repair
[Zw4...] Quick Check OK

Unpack
[Zw4...] Trying unrar with password "lxw4..."
[Zw4...] Unpacked 733 files/folders in 4 mins 48 seconds
---  everything seems fine at this point, and then 7zip ... ---

[00002] Trying 7zip with password "lxw4..."
[00004] Trying 7zip with password "lxw4..."
[00003] Trying 7zip with password "lxw4..."

Can you share such a .NZB file, for example via https://www.file.io/ ... and then share the link, which will be something like https://limewire.com/d/QkFblabla

Thanks to +Debug option, there are some zip files for this UHD folder.

Re: Unpacking failed, see logfile -- 7zip

Post by sander »

TLDR: there are zip files, and SAB tries to unzip (which fails), and I think SAB should not try to unzip those files deep down in a BDMV structure. Hopefully safihre reads this and can say something clever.


Ah, a 60GB BDMV download.


During unpack ... yes, there are zip files.

Code: Select all

sander@DrDr:~/Downloads/complete$ find . | grep -i -e zip$ -e 7z$
./_UNPACK_5adcf1aca3e5f9882181d709/BDMV/JAR/01010/00004.zip
./_UNPACK_5adcf1aca3e5f9882181d709/BDMV/JAR/01010/00003.zip
./_UNPACK_5adcf1aca3e5f9882181d709/BDMV/JAR/01010/00002.zip
./_UNPACK_5adcf1aca3e5f9882181d709/BDMV/JAR/01010/00001.zip
I think SAB should not touch that.

While still unpacking: no touching of the zip files, so good:

Code: Select all

$ cat ~/.sabnzbd/logs/sabnzbd.log | grep "2026-04-08" | grep -i -e zip -e 7z

Unpacking took 8 minutes on my machine. And what happens then ... ?

...
... so SAB starts working on those zip files (which I think it should not do), with the password, and SAB says "Unpacking failed, see logfile".

Not good.


FWIW:

Manual unzip says

Code: Select all

$ unzip 00001.zip
Archive:  00001.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of 00001.zip or
        00001.zip.zip, and cannot find 00001.zip.ZIP, period.

Will give that a try. Thanks.

[UPDATE] Confirmed that download was successful by unticking "recursive unpacking"
