Just realised I have par2cmdline 0.8.1 on my Debian host server, I should have tested it with that too, but I've deleted the rar's now. Will test again if I encounter another failure.

TIL: If manual par2repair gives better results than SABnzbd's par2repair, first step is to have the default par2 settings in SABnzbd ... meaning "Extra PAR2 Parameters" ... empty. That won't always be the case... adding '-N' to Extra PAR2 Parameters used to give better results, however, I...

I added because of the same problem... perfectly repairable downloads were being identified as non-repairable :D Adding the '-N' tells par2 that you want "No data skipping" (https://manpages.ubuntu.com/manpages/xenial/en/man1/par2.1.html). It makes sure the the whole file is scanned and ca...

I've removed '-N' from the Extra PAR2 Parameters field, gone into history and hit Retry. This time around it has successfully repaired, unpacked and deleted.

So it scans the right files but finds less blocks when we specify exactly which files to scan? I've just copy/pasted the command from the log file which specifies 94 rar files and 9 par2 files and it doesn't find enough blocks: https://pastebin.com/rWLrEh1V This works: par2 v Debian.Linux.12.4.iso....

Yeah:

Running par2verify finds the additional blocks though: /downloads/sabnzbd/incoming/Debian.Linux.12.4.iso # par2verify Debian.Linux.12.4.iso.par2 Loading "Debian.Linux.12.4.iso.par2". ... ... Target: "Debian.Linux.12.4.iso.part027.rar" - damaged. Found 32 of 33 data blocks. Openin...

Also, manually running this simple command gives odd results: /downloads/sabnzbd/incoming/Debian.Linux.12.4.iso # par2 v -N Debian.Linux.12.4.iso.par2 Loading "Debian.Linux.12.4.iso.par2". ... ... Target: "Debian.Linux.12.4.iso.part027.rar" - damaged. Found 9 of 33 data blocks. 1...

Hi, So I ran par2verify <par2 file> so that it didn't actually perform the repair this time and got this: Par2Verify Output: https://pastebin.com/BGNEDDdM While this is the Sab log: https://pastebin.com/7YFTs8du It's not finding anywhere near as many data blocks within the corrupted files. It helpfu...

The command that successfully repairs the archives is just: par2repair <rarfile.par2> There's still nothing interesting in the log file, even though a second download failed this morning. I've spotted that the log_level set to 0 in my config file though, have set to 2 now and will report back once m...

Hey, everyone, I've noticed that I'm getting a "Repair failed, not enough repair blocks" error quite often, but it's not accurate. A download failed just now saying that it was 202 files short, but when I drop to the command line and run par2repair it was fine: Repair is required. 30 file(...

Hi, I have been looking at the same thing as you have (I know this is a little late but it could help others so I'm posting). I took the same source script as you did but I made a number of modifications so that it looks up the language of each embedded subtitle rather than trying to guess it. I als...
