What are the contents of your /etc/apt/sources.list?

Hi James,
My sources.list contains:

$ more /etc/apt/sources.list
#deb cdrom:[Debian GNU/Linux 12.2.0 _Bookworm_ - Official amd64 NETINST with firmware 20231007-10:28]/ bookworm main non-free-firmware

I suspect the error may have been caused by attempting to install tt-rss, which seems not to be supported in trixie.

This issue is caused by comments being present in the /etc/apt/sources.list (yep, I messed up :slight_smile: ). Distribution upgrade has not been triggered and you system is in same state as before you have triggered distribution upgrade.

For fixing this you will need the latest freedombox package from bookworm-backports (version 25.9.3~bpo12+2). This version likely reached you already as it was made available on Aug 12. You can simply try re-triggering the distribution upgrade. If the problem persists, let us know.

@Sunil , Thank you! It doesn’t appear to be on my system yet. Will let you know what happens after it arrives.

@sunil, I gave it a few tries over the past couple of weeks, but still getting this error when I attempt a distro update:

Do you have freedombox version 25.9.3~bpo12+2 from bookworm-backports? That is the version the contains the fix. You can also overcome the problem by removing comments from /etc/apt/sources.list. If that does not fix the problem, please post your /etc/apt/sources.list file.

@Sunil That’s missing from my sources.list:

@nomadicoder Your sources.list already contains “Trixie” (Debian 13) instead of “Bookworm” (Debian 12). Have you manually updated it? Or did you run FreedomBox distribution upgrade already? Anyway, remove the lines with comments to get rid of the error you are facing.

I think the distribution update ran 12 hours ago, after I sent the reply with error and an hour after your reply to that. I looks like all is well now.

Thanks for clearing things up!
