Suddenly, i would get a 502 Bad Gateway page while trying to access my localhost nginx web server.<\/p>\n
Looking at nginx log, found these I remembered having firing the system updater few hours ago. Looking at the logs I see php5-fpm, php5-mysql, php5-common, php5-readline, php5-cli have been updated. I guess this is what caused the breakup.<\/p>\n I tried re-installing them I ran Apparently the last update didn’t complete. But i’m still getting the 502 error :-\/<\/p>\n But then googling more about the nginx log, someone posted a magical solution here<\/a><\/p>\n Problem Solved \ud83d\ude00<\/p>\n","protected":false},"excerpt":{"rendered":" Suddenly, i would get a 502 Bad Gateway page while trying to access my localhost nginx web server.

\nYou might want to run 'apt-get -f install' to correct these:
\nThe following packages have unmet dependencies:
\n libwebkitgtk-3.0-0 : Depends: libjavascriptcoregtk-3.0-0 (= 2.4.2-1ubuntu0.1) but 2.4.3-1ubuntu2 is to be installed
\nE: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
