[Bug 1779157] Re: /usr/bin/unattended-upgrade:AssertionError:/usr/bin/unattended-upgrade at 1927:main:do_install

[Balint Reczey]

The problem seems to be gone on errors.ubuntu.com.
There are a few errors falsely reported against the fixed version (1.1ubuntu1.18.04.4) but those are cases where the buggy version upgraded the package and afterwards apport collected the version of the fixed package, which did not run yet.

Also note that in the stack trace the u-u versions are mixed,
only 1.1ubuntu1.18.04.1 raises the error at line 1065 in do_install,
but the "if dpkg_log_content:" is from 1.1ubuntu1.18.04.4.

Traceback (most recent call last):
  File "/usr/bin/unattended-upgrade", line 1935, in <module>
  File "/usr/bin/unattended-upgrade", line 1790, in main
    cache, auto_removable_kernel_pkgs,
  File "/usr/bin/unattended-upgrade", line 1065, in do_install
    if dpkg_log_content:
AssertionError: Internal error. The following packages are marked for removal:linux-modules-extra-4.15.0-23-generic
