Thanks in advance!

@egorix,

Try

sudo apt-get clean && sudo apt-get update && sudo apt-get upgrade

Same problem here, on all my systems.
apt-get clean wont work :frowning:

One can try uninstall and then reinstall. I had to uninstall webmin and virtualmin and all settings were intact fortunately which is very helpful.
