Fatal error failed to load steamstartengine(oxffd66000) failed with error 1: CMultiFieldBlob(pSerialized): Partial Field head at end of record

[Carthaginho]

Hello I have this message when I want to start Steam.
Someone has a solution?

Thanks for helping.

I haven't seen this issue on Linux for steam before, however I do believe I have seen something similar on OSX.

It was caused by Steam not shutting down properly and it still looked like it was running. You could attempt to track down the item in the System Manager or try a simple reboot.

(this might not be the actual issue though)

I have found the solution to fix it.
In first write in the terminal: cd ~/.steam/steam and in second write: rm ./ClientRegistry.blob

Enjoy !

Thanks man¡¡¡

This is interesting, it sounds like the ClientRegistry can become corrupt. Did you notify Valve about it? There must be something causing it.

Didn't this happen in Windows at one time? I remember having to delete it every now and again, a few years ago. Haven't had to do it for a while.

Apparently it can happen if Steam is shutdown unexpectedly :

Where you open the terminal from depends on which Linux you're using.

If you're on Ubuntu open the Dash (press the "windows" key on your keyboard or click the Ubuntu icon in the launcher) and type the word terminal.

An alternative which should work on most versions is to press ALT and F2 and put this command directly in there:
rm ~/.steam/steam/ClientRegistry.blob

The advantage of putting command in full terminal window rather than using ALT+F2 is that you get feedback about whether the command worked or not!

If you want to do everything by the GUI then here are the steps:

open your file browser
go to your home directory
unhide hidden files and folders (often Control + h or look for the option in a menu)
go into the .steam directory
go into the steam directory
find and delete the ClientRegistry.blob file


Here's a quick explanation about what the terminal command means:
rm - just mean remove / delete a file or directory.
~ - is a quick way of saying you're doing stuff in your home directory
/ - separates directories (NB windows uses \ for some silly reason)
. - before a file or directory name means it's hidden

It really depends what distro you're using. Distros with more traditional interfaces usually list the terminal emulator in either of these places:

Application Menu > Accessories > Terminal
Application Menu > System > Terminal

If you're using Ubuntu or Mint you can use their default shortcut Ctrl + Alt + T.

If you're really struggling to find the terminal emulator you can always use Ctrl + Alt + F1 to get into a real terminal and then Ctrl + Alt + F7 to get back to your desktop.

if you are not able to fix it, wait a week or two and it should fix itself- it happened for me
