dnf list --installed: wrong colors

[CanePlayz]

I've read that red packages mean that they are no longer available through any installed repo. However, on my machine, all packages listed under dnf list --installed appear red. Is there any piece of documentation on the colors?

There is https://dnf.readthedocs.io/en/latest/conf_ref.html?highlight=color#main-options-colors.
I think the colors also depend on your terminal and its configuration.

Thanks, I somehow missed the "default" part in there. I still don't get why all my installed packages are marked red when they work fine and I can update them just fine, but I guess it's okay as long as they work. Or is there anything we can do to try to solve this?

I have looked into it more and you are correct, there is indeed a bug when running with the --installed flag.

The problem is dnf is optimized to not even load information about available packages when the --installed flag is used, it just loads the system repo. Given that this information is needed for correct coloring it breaks.

Thanks for digging into it, that makes sense.

We have discussed this internally and the best solution we came up with would probably be to turn off the wrong colors in this case.
This command is expected to work correctly even when the remote repos are not available.

However, given that our primary focus is dnf5 we will most likely not be fixing the issue. Contributions welcome though if anyone would be interested.

We have a workaround: dnf list --color=always | { sed -n '/31m/p; /Available Packages/q'; cat > /dev/null; }

dnf list without --installed first list the installed packages then it show Available Packages (this string is localized) then the list of available packages.

So this sed invocation cut when yum have finished to print the first part. The cat is to avoid broken pipe error from dnf trying to write on a closed pipe.

Also in the first part without --installed it will display correct color (only red for missing packages) so we used this: -n '/31m/p;' it is basically a grep on the escape sequence used by yum (red).

The only thing missing is how to say to yum to not wrap (since it is not a pty it wrap at 80 so repository might get on another line and not visible so you need to do yum list x after. It is still useful to see missing packages.
