Title: Flashing OPNSense .img.bz2
Post by: Ze_Mind on April 18, 2026, 09:35:37 PM
I don't know where this goes. move if needed.

When I flash this with Etcher, it gives me an error.

Something went wrong. If it is a compressed Image, please check that the archive is not corrupted. Error starting flasher sidecar process.
When I go to extract the img.bz2 file, all it does is hang. Not making it past 20%.

There something wrong with your files, or is it just me? I tried this on Debian as well on Mint. So it's not OS dependent.

Running Debian Testing KDE Plasna.

Have you tried doing a "bzip2 -d" first?

Yes, I have done that "bzip2 -d" command. Again, it just hangs.

Here is the .img file I saved after I had extracted the original .bz2 file a while ago with
$ bzip2 -dv https://drive.proton.me/urls/MYEC8EHCQ0#BtMc88nHoTpx

And succesfully flashed to my USB Stick afterwards with the following dd command :
# dd of=/dev/sdb if=OPNsense-26.1.2-vga-amd64.img bs=4MiB status=progress
See if you can do the same :)



The reason I uploaded it for you is that the OPNsense Update Procedure can sometimes be picky/weird when it's done over a Mobile Broadband Connection so I thought maybe you are having similar issues with one of the OPNsense Mirrors and could use an alternative ??

Hope it works better this way...

I have been able to download an earlier version, 25.7, that worked fine for me.

I do not think it is mirror dependent.

But I'll download the img file and see how it goes.

Update: I finally got it flashed. Weird how this happens.

I asked a good friend of mine to download it and try to extract the img.bz2. He couldn't either. Says it was done, but got corrupted.
