My linux PC has suffered the occasional application crash, desktop crash, and kernal panic over the last few months. I also started noticing error dialogs on login, and some parts of the desktop do not look the same. Over the last week, this crash rate has increased to more than 3 per day, so I investigated with logs and diagnostics.The MemTest86 program indicated a memory module fault. I removed the faulty module and my system is now stable.My problem is there are many inital errors and small failures (eg: cups printing, an icon missing from the toolbar, the purple bacground disappeared from the Ununtu boot screen, etc), that suggest bit errors during configuration writes or apt-get upgrade binary updates.Is there a apt-get checksum all-packages type command that can check my binaries with a global repository (and perhaps re-install corrupted files)?Debian installs have the debsums utility (as mention here: Check and fix all files from Debian packages.). Is there a similar utility in the Ubuntu world (using apt)?I would like to avoid a complete re-install of OS and all applications.OS: Ubuntu 14.04.2 LTS (14.04) 64 bit
