apt.systemd.daily: fix error from locking code
Error:
pkgs that look like they should be upgraded:
Error in function stop
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/apt/progress/text.py", line 240,
in stop
apt_pkg.size_to_str(self.current_cps))).rstrip("\n"))
File "/usr/lib/python3/dist-packages/apt/progress/text.py", line 51,
in _write
self._file.write("\r")
AttributeError: 'NoneType' object has no attribute 'write'
fetch.run() result: 0
Caused by:
LOCKFD=3
unattended_upgrades $LOCKFD>&-
Unfortunately this code does not work, it is equivalent to
unattended_upgrades 3 >&-
I.e. it left fd 3 open, but closed stdout!
Closes: #862567
