You > just need to follow the LTS workflow [0]. Thanks. I updated dla-needed. The fixed packages are ready for upload now. Please find the full debdiff (source and binary) attached to this email. Note that the (seemingly) added dependency on libxtables7 is a no-op. It's a virtual package provided by iptables (which is a dependency already). Apparently, there was some change after the original wheezy upload that's causing this to now show up. Similar, the new dependency on zlib1g shouldn't make a difference either. The package has priority=required. Not sure why it's now showing up in the dependencies but didn't previously. I'll wait for your "Go" to actually upload the package. Then, I'd go ahead to claim an DLA as documented. Should I wait for and synchronize with the DSA or should I come up with my own text?
