Sorry if my previous comment came across as rude, it wasn't intended as such. It was just meant as a quick reply (I was in a hurry) to clear up what is the topic of this bug as incomplete reports aren't actionable.
(An incomplete bug isn't necessarily the fault of the bugreporter as someone can hardly think of everything and/or an important fact to know for upstream isn't obvious to someone who isn't deeply involved with the package in question. So, no critic meant either.) So, with my apt upstream hat, I am reassigning to dpkg even through I know that this is caused by a change in apt, but the problem is that dpkg has a non-overrideable check for terminal output or not (and because as mentioned apt quiet option never influenced dpkg. Otherwise quiet=2 wouldn't have output at all, but what it does is in fact reduce the output to mostly just dpkg output). The apt change in question is that dpkg is properly called in (most) cases in a pseudo-terminal, so it's looking always like dpkg is running in a terminal. We need this in apt to be able to log the output (term.log) as well as show the output of dpkg (and subsequently programs called by it like debconf) correctly. See e.g. debbug #765687. The 1.0.9.x versions contain various fixes (and fixes of fixes) in this regard. You can tell apt to not use a pseudo-terminal for dpkg with -o Dpkg::Use-Pty=0 , but that carries all the disadvantages I mentioned earlier and more and is therefore not advised. ** Package changed: apt (Ubuntu) => dpkg (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1448917 Title: apt-get -o quiet=1 dist-upgrade isn't quiet anymore Status in dpkg package in Ubuntu: New Bug description: Description: Ubuntu 15.04 Release: 15.04 apt: Installed: 1.0.9.7ubuntu4 Candidate: 1.0.9.7ubuntu4 Version table: *** 1.0.9.7ubuntu4 0 500 http://de.archive.ubuntu.com/ubuntu/ vivid/main amd64 Packages 100 /var/lib/dpkg/status Current: Until updating from Utopic to Vivid apt-get with command line parameter "-o quiet 1" did not output the progress as formatted text. Since the update the progress is written to stdout as formatted text. This breaks a lot of scripts, e.g. the cron-apt package with mail send enabled. The attached text is no longer text only and will be encoded as binary, so the mail is unreadable. Expected: Same behaviour as with version from Utopic, no progress output To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/1448917/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
