I am experiencing the same thing...
***************
. adoupdate xtabond2, update verbose
(note: adoupdate updates user-written files; type -update- to check for
updates to official Stata)
Checking status of specified packages...
[104] xtabond2 at http://fmwww.bc.edu/repec/bocode/x:
package has been updated on server
Packages to be updated are...
[104] xtabond2 -- 'XTABOND2': module to extend xtabond dynamic panel
data estimator
Installing updates...
[104] xtabond2
----------------------------------------------------------------------------
------------------------------------------------------------
-> . net set ado PLUS
-> . ssc install xtabond2, replace
checking xtabond2 consistency and verifying not already installed...
all files already exist and are up to date.
----------------------------------------------------------------------------
------------------------------------------------------------
Cleaning up... Done
****************
Browsing around the Statalist archive on the 'adoupdate problems' I found
that it seems to be caused by "an inconsistency in the metadata" in the SSC
archive.
