oh, just great. :-/

now i understand/know. thanks.

ok, given two 'identically named' (even though they're differen :-/ ) file,

  % smart query --show-summary --show-channels
MozillaThunderbird-1.99.1-44.1 at i586
   MozillaThunderbird-1.99.1-44.1 at i586 [suse-mozilla-latest] - The
Stand-Alone Mozilla Mail Component
   MozillaThunderbird-1.99.1-44.1 at i586 [myDB] - The Stand-Alone
Mozilla Mail Component

i _can_ get the --show-all output of JUST the installed version in [myDB] with,

  % smart query --show-all --installed MozillaThunderbird-1.99.1-44.1 at i586

but how do i get the output for JUST the one in [suse-mozilla-latest]?


for the moment, i did a,

  % smart query --show-all MozillaThunderbird-1.99.1-44.1 at i586

and manually split the output into two files,

	TBird_in_myDB.txt
	TBird_in_suse-mozilla-latest.txt

then,

diff -ur TBird_in_myDB.txt TBird_in_suse-mozilla-latest.txt

in spite of the diff==NULL, there apparently *is* a difference,

ok.  *now* it's *really* the 'same'.

checking,

  % smart upgrade MozillaThunderbird
    No interesting upgrades available.

so, i understand WHAT happened.

questions, still,

WHY? --> iiuc, as you explained ...

WHAT TO DO ABOUT IT?

i'm assuming this will be the same problem with 'all' the other
packages being force-downraded-to-upgrade.

should I,

	(a) rebuild the 'master' rpm DB?
	(b) delete, then re-create [myDB]?

what's recommended here?

thanks.
