Test Case
---------
1) edit /etc/apt/apt.conf.d/20auto-upgrades so that Update-Package-Lists is 1 and Unattended-Upgrade is 1
2) sudo apt-get update
3) sudo /usr/bin/unattended-upgrades (to update the system)
4) sudo /usr/bin/unattended-upgrades (a second time for some reason)
5) sudo rm /var/log/unattended-upgrades/unattended-upgrades-dpkg.log
6) sudo /usr/bin/unattended-upgrades
Observe the following crash:
Traceback (most recent call last):
File "/usr/bin/unattended-upgrade", line 1468, in <module>
main(options)
File "/usr/bin/unattended-upgrade", line 1406, in main
log_content = get_dpkg_log_content(logfile_dpkg, install_start_time)
File "/usr/bin/unattended-upgrade", line 1075, in get_dpkg_log_content
with io.open(logfile_dpkg, encoding='utf-8') as fp:
FileNotFoundError: [Errno 2] No such file or directory: '/var/log/unattended-upgrades/unattended-upgrades-dpkg.log'
With the version of the package from -proposed you won't receive the
crash in step 6 and /var/log/unattended-upgrades/unattended-upgrades-
dpkg.log will exist.
Regression Potential
--------------------
This patch just ends up creating a file if it does not exist. Potential regressions would be a result of the patch being typo'ed e.g. typo'ing os.path.exits instead of os.path.exists and the code failing when a logfile does exist. So read the patch carefully!
