apt-get upgrade for sudo fails with segmentation fault

[Chris Jones]

Hi,

I have a new installation of hardy (on a pendrive, if this matters).

apt-get wants to update sudo, but whenever I do I get the error

Fetched 2555kB in 26s (94.8kB/s) 

Preconfiguring packages ...
(Reading database ... 101614 files and directories currently installed.)
Preparing to replace sudo 1.6.9p10-1ubuntu3 (using 
.../sudo_1.6.9p10-1ubuntu3_i386.deb) ...
Unpacking replacement sudo ...
E: Sub-process /usr/bin/dpkg received a segmentation fault.

and the update fails.

sudo seems to work fine.

Anyone else seeing this ? Any ideas whats up ?

cheers Chris
