Error trying to update webmin and usermin

Hello,

I just renewed my license and tried to update the following packages:

webmin web-based administration interface for Unix systems 1.560 usermin web-based user account administration interface for Unix systems 1.480

When hitting the "Install all updates now" -button I get the followin error messages: Now updating webmin .. Installing package(s) with command apt-get -y install webmin .. Reading package lists... Building dependency tree... Reading state information... The following packages will be upgraded: webmin 1 upgraded, 0 newly installed, 0 to remove and 14 not upgraded. Need to get 14.8MB of archives. After this operation, 143kB of additional disk space will be used.

WARNING: The following packages cannot be authenticated! usermin E: There are problems and -y was used without --force-yes .. install failed!

No packages were installed. Check the messages above for the cause of the error.

How come and how do I do to install without this error messages?

Can you try logging into the command line as root over SSH, and try that again by running this command:

apt-get update && apt-get upgrade

If that doesn't work -- can you post a copy of your /etc/apt/sources.list file? Thanks!

I just tried to upgrade, I think v1.560 to current 1.570 , and got the below error message, then no responses on server, rebooted, Webmin not running, I started with init.d and it seems mostly there but I think maybe missing some things.

Below is error message, running on Debian 5.0.

(Reading database ... 31731 files and directories currently installed.) Preparing to replace webmin 1.560 (using .../.webmin/518963_2_upgrade.cgi) ... Unpacking replacement webmin ... dpkg: dependency problems prevent configuration of webmin: webmin depends on apt-show-versions; however: Package apt-show-versions is not installed. dpkg: error processing webmin (--install): dependency problems - leaving unconfigured Errors were encountered while processing: webmin

I don't frequently touch this machine, it was running something like 300 days before restart with little maintainance. Any ideas? Thanks. I'm just now getting apt-show-versions, and after that, I see "Webmin install complete" so maybe everything is good now.

How did you attempt the upgrade?

If you log into your server as root, and type:

apt-get install webmin

Does that work without any errors?
