Comparing packege sets of two tumbleweed installs

English Install/Boot/Login
1

Hi all,

So I have two machines both running tumbleweed, though one was a migration from Leap, and the other a native TW install.
Is there an easy way of exporting the list of installed packages on both systems so that I can find the packages installed on one that are not on the other?

I hopefully want to do this to see if I can chase down my xrdp problems, it works one one and not the other.

Cheers.

Phill.

Sure, I don’t know how familiar you are with bash scripting, but you would begin with

rpm -qa > pkgs-$HOST

on each. That would give you 2 sets of all installed packages

And then transfer one of those to the other system.
And use the diff command?

Better yet, use the --qf (--queryformat) option for some more fine control about the fields that you want to see, and of course sort the result to be able to use diff:

sh@meteor:~> rpm -qa --qf '%{name}  %{version}-%{release}\n' | sort
