I strongly disagree! The space was put in the URL by the original corefonts SourceForge project way back in 2002, and has been there since then! The space was there when apt 1.2.12~ubuntu16.04.1 successfully handled the redirects on 2016-09-26 and on 2016-11-04. Now apt 1.2.15ubuntu0.2 fails the handle the space, and that is quite simply called a regression. Also, the failure that I report is more complex than mishandling space encoding, see the bottom of comment #1 for the weirder part (various HTTP failures depending on.. the presence of the target file on disk). -- 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/1655431 Title: apt-helper / update-notifier / ttf-mscorefonts-installer download failure (regression) Status in apt package in Ubuntu: Confirmed Bug description: * OS release: Ubuntu 16.04.1 LTS * Package version: 3.168.3 For the past few days (maybe even weeks for other users), update- notifier has been very repeatedly failing to handle the downloads for ttf-mscorefonts-installer. Previously it was working fine on the same system. This seems to affect a lot of desktop users, but the issue is usually misdiagnosed on forums because it is attributed to ttf-mscorefonts- installer and not to update-notifier-common. The issue is made particularly irritating because the update-notifier cron job tries and fails and notifies users daily of this failure. The issue can be reproduced by having ttf-mscorefonts-installer installed, and running: sudo dpkg-reconfigure update-notifier-common The error messages seem to be random but actually appear to be consistent for a given download source: * freefr.dl.sourceforge.net: 404 Not Found * kent.dl.sourceforge.net: Protocol "http" not supported or disabled in libcurl * netassist.dl.sourceforge.net: The HTTP server sent an invalid Content-Range header Bad header data [IP: 62.205.134.42 80] * netcologne.dl.sourceforge.net: The HTTP server sent an invalid Content-Range header * netix.dl.sourceforge.net: 404 Not Found * vorboss.dl.sourceforge.net: 404 Not Found In all above cases, the reported failing URL can be downloaded just fine using wget. Some other mirrors appear to work (unfortunately, mirror names are only printed in case of errors). However, since ttf-mscorefonts- installer triggers 11 downloads in a row, chances of randomly getting 11 working mirrors are very low. I am tagging this as regression-update because the issue started happening when upgrading from 3.168.2 to 3.168.3 last Friday. It is of course entirely possible the root cause is in another package, but this would also likely be a regression-update, since I am very careful about system-wide changes on this machine. The previous update from 3.168.1 to 3.168.2 on November 4th went just fine. ttf-mscorefonts-installer has been installed (just fine) on September 26th, and not upgraded since then.
