Looking at manpages for previous releases of Ubuntu they all contain the same information about --full for journalctl. I did find lines being ellipsized in a DpkgTerminalLog.txt file. Is that what you were looking at? An example:
Instalowanie nowej wersji pliku konfiguracyjnego /etc/apparmor.d/abstractions/libvirt-qemu ...

The actual error information is this: /etc/ssh/sshd_config line 64: miss.... and Failed with result 'e.... This is very nearly useless. We should include the -l parameter as suggested so that we stand a chance of seeing an error that doesn't occur in the first twenty characters of program output.
