I would bet that you most likely had your -security uploads rejected due
to the versioning not matching the Security Team scheme and not your
-updates uploads. The Security Team is picky about versioning in
-security (rightfully so, IMO).
I try to be picky/consistent about it when sponsoring to -updates but
what happens a lot of times is that the previous SRU for the given
package used a more "lax" versioning scheme and the Security Team scheme

The Security Team has had really good success with the documented
versioning scheme. There are some minor corner cases where -security
uploads have had to deviate slightly. I want to say that mostly had to
do with "security fake syncs" where a Debian package is manually synced
to -security. Maybe a current security team member has more recent
memories than I do and can comment. OTOH, I'd say the scheme works %95
of the time and the scheme can always be updated once the other 5% is

+1 from me for adopting it. I don't enjoy the inconsistency when I'm
sponsoring uploads because I feel like I'm nitpicking about something
that's not widely used/adopted.
