Comment 3 for bug 1969477

>If direct access to Launchpad is blocked how was a bug report filed in the first place?

Clicking the "Report a Bug" link on any project's page in LP. This is done from a machine outside of the airgapped or restricted access lab where the hardware sits.

Also, I should point out (which I mentioned originally) that one can, and I'll also start suggesting they do this, use --save with ubuntu-bug to create a bug report that can be submitted later from a different machine.

I'm just asking to have apport-collect also feature this...

Perhaps the solution since, as you pointed out, apport needs to read the bug to know which package to collect files for, is to require the package as part of the commmand... e.g.

apport-collect --save=/path/to/filename --package=$PACKAGE $BUG_NUMBER
