$ ubuntu-bug /var/crash/<NAME>.crash does not work

[Impact]
1. When trying to send a report manually, you can not
2. When next possibly unrelated crash of same process happens, <NAME>.crash gets overwritten even when <NAME>.crash.upload exists (upload not yet completed)
3. When trying to copy-paste the stacktrace as text, UI does not have such functionality

[Test Case]
Start Ubuntu
Open terminal
$ ubuntu-bug /var/crash/<NAME>.crash # does not appear to send anything to errors.ubuntu.com, when NetworkManager claims missing network connectivity.

In multihomed host renderer: networkd in netplan with some of the redundant bridge members lacking physical connectivity and/or offline usb tether backup networks tend to result in perfectly functional state = "routable" network that many ubuntu GUI tools refuse to work with anyway, is apport one of them?

Similarly to bug #1825822 I attempted to

$ ubuntu-bug /var/crash/_usr_lib_xorg_Xorg.1000.crash # but after clicking "Send" the /var/crash/_usr_lib_xorg_Xorg.1000.upload does not change into ".uploaded". And before the "Send" the UI does not contain any obvious way to copy the report as text somewhere (note: just copy the .crash which is text format with base64 parts anyway, at least for now).
