Installing -0ubuntu6.9 resolved the issue. Reinstalling -ubuntu6.10 broke the system again. I note that -ubuntu6.10 was recently added to the archive. I am currently unable to install Ubuntu 14.04.5. ------------------------------------------------------------------------ [2017-03-22 11:16:58] alex at 1200wd dot com For people like me that happened to stumble on this: Checking my apt logs the following packages were updated at that time: - libxml2 - libc-bin This happened on an ubuntu 16.04 server with php7. ------------------------------------------------------------------------ [2017-03-22 10:33:52] spam2 at rhsoft dot net sorry, but i don't get how ideas like "oh, my distribution updated libc and something broke, i will report a bug on the victims upstream bugtracker" are growing ------------------------------------------------------------------------ [2017-03-21 22:46:11] nikic@php.net @rhsoft: It would be much appreciated if you could tone down your comments a bit. They are commonly passive aggressive, sometimes downright rude and contribute to a somewhat unpleasant atmosphere on this bug tracker. ------------------------------------------------------------------------ [2017-03-21 21:55:14] spam2 at rhsoft dot net and why don't you write a bugreport on the ubuntu bugtracker instead upstream? most likely some library update broke the PHP installation - both is from ubuntu and PHP 5.6 is more or less EOL at all and another question: who does "automated updates" and then complains at upstream bugtrackers that some unattended downstream stuff broke whatever? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
