debian 4.0 3.48.gpl (GPL) upgrade

I insert in sources.list virtualmin repo and after that I run this commands [code:1]echo "upsource=http://software.virtualmin.com/gpl/wbm/updates.txt http://www.webmin.com/updates/updates.txt" >>$webmin_config_dir/etc/webmin/webmin/config echo "upthird=1" >>$webmin_config_dir/etc/webmin/webmin/config echo "upshow=1" >>$webmin_config_dir/etc/webmin/webmin/config[/code:1]

I login on my virtualmin control panel and I click on install all update

After that, I restart the server and I relogin to virtualmin but it is still 3.48

I click on install all updates but all the installations failed.
