Frequent aptitude upgrade error

I often encounter this error when using aptitude to upgrade my Devuan ASCII system:

# aptitude update && aptitude upgrade

No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.

If I comment out backports and try again, the problem goes away. My guess is that someone has messed up and did not properly rename one of the packages in backports. Of course, I could be wrong. Any thoughts?

Have you tried using deb.devuan.org as per https://devuan.org/os/etc/apt/sources.list and https://files.devuan.org/devuan_ascii/Release_notes.txt  ?

Thank you for the suggestion. Yes, I did, and the problem remains.

Re: Frequent aptitude upgrade error

Do you know which packages from backports are causing the problem? Get the list of bpo packages that are to be upgraded, and run 'apt-cache policy' on them to see what versions are in ascii and bpo. That might identify the naming problem you suspect. It might also be possible to find the problem by upgrading one bpo package at a time. (one or a few if necessary.)

Re: Frequent aptitude upgrade error

I did a little more detective work on this today. I found three packages from Jessie that were, for some reason, never removed when I upgraded to ASCII.

$ apt-show-versions -u
remmina:i386/ascii-backports 1.1.1-2 upgradeable to 1.2.32.1+dfsg-1~bpo9+1
remmina-common:all/ascii-backports 1.1.1-2 upgradeable to 1.2.32.1+dfsg-1~bpo9+1
remmina-plugin-rdp:i386/ascii-backports 1.1.1-2 upgradeable to 1.2.32.1+dfsg-1~bpo9+1

After removing them the problem seems to have gone away, at least for now.
