I cant even uninstall webmin

this is an error I get

E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

something about lock and another process using it ?

please help

This error has nothing to do with Webmin or Virtualmin. You've got multiple apt-get or dpkg processes running (or something broken somewhere in dpkg or apt-get).

And what do you mean by "missing modules"? I don't see any errors regarding missing modules here.

hi , it's actually in webmin. when i try to install a missing module like apache .. even thought i had installed it . there is an option to Click here to have it downloaded and installed using APT. when i try that I get the above error.
so i cant use the program either webmin or virtual.

so how ca i fix my problem if there are multi apt-get working ,, how can i close them ??

Apache is a standard Webmin module. You should never have to install it.

It sounds like you're using some non-standard Webmin package, like maybe the one from the Debian 3.1 repositories, which is horribly broken.

Remove the broken Webmin package, and install the one from Webmin.com (a .deb is available).

Same error here. Increasing SWAP memory to 4096MB solved the issue.

Using Virtualmin GPL installation script (install.sh) on Ubuntu Server 8.04.1, VPS hosting, XEN, 360MB RAM, 4096MB SWAP. 4096MB SWAP is overkill though less might work.
