Just saw this new error trying to upgrade a Centos 5.8 box via CM

Which Webmin version is that system running?

This could happen if Webmin is really old, but other modules are new.

Operating system CentOS Linux 5.8
Webmin version 1.600
Virtualmin version 3.95.gpl GPL

Does running /etc/webmin/restart help?

I wont know that until the next package upgrade for a program

So in this case, did util-linux actually get updated OK?

No I had to login and manually upgrade that package
