Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Thank you for the bug report. I tried to reproduce the problem but could not and I suspect it is caused by an other issue with the system.

In .var.log.apt.history.log.txt i see dpkg starting to fail earlier:
...
Start-Date: 2019-01-15 10:10:08
Commandline: apt-get install apache2
Requested-By: lenovo (1000)
Install: apache2:amd64 (2.4.29-1ubuntu4.5)
Error: Sub-process /usr/bin/dpkg returned an error code (1)
End-Date: 2019-01-15 10:10:23
...

If you have more information on how the issue can be reproduced on a clean system please share it in this bug report.
