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 (cherry picked from commit 7b4581cbe8fcf6e2bd56a27c5a7a1e6ea33d2973) (cherry picked from commit 3310f862cba0b997ede8fc4e2d270ab0f6b49e73)
