No user exists for uid 501 after XQuartz update?

[peeterjoot]

I just installed an update (2.7.11) for XQuartz, logged out and logged in, and am now getting weird UID related errors attempting to ssh out of my mac:

$ ssh macbook

No user exists for uid 501

The error appears to be a local error on the mac itself, not a network issue.

This id is in fact my uid:

$ id

uid=501 gid=20(staff) groups=20(staff),12(everyone),61(localaccounts),79(_appserverusr),80(admin),81(_appserveradm),98(_lpadmin),701,33(_appstore),100(_lpoperator),204(_developer),395(com.apple.access_ftp),398(com.apple.access_screensharing),101



$ echo $UID

501

but id doesn't recognize it explicitly:

$ id -u 501

id: 501: no such user

$ echo $USER

pjoot

$ id pjoot

id: pjoot: no such user

$ cd

$ ls -ld .

drwxr-xr-x+ 81 501 staff 2754 30 Nov 18:52 .

I also don't appear to be able to run sudo anymore:

$ sudo vim /etc/passwd

sudo: unknown uid 501: who are you?

(I thought I'd try to hack in an /etc/passwd entry for id=501 for myself).

The highest entry I have in /etc/passwd now 252:

...

_ondemand:249:249:On Demand Resource Daemon:/var/db/ondemand:/usr/bin/false

_xserverdocs:251:251:OS X Server Documents Service:/var/empty:/usr/bin/false

_wwwproxy:252:252:WWW Proxy:/var/empty:/usr/bin/false

My suspicion is that the XQuartz update has messed things up. How can this be repaired?

A reboot appears to have fixed this issue.
