我正在努力使用 Clamav，无论我做什么，我都会收到错误
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package clamav is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'clamav' has no installation candidate
我试过
sudo apt-get -f install
sudo apt-get update
sudo apt-get upgrade
然后
sudo apt-get install clamav
然后
sudo apt-get install clamav clamtk
而不是从软件中心，但是没有运气。
有人可以帮我安装 ClamAV 吗？

确保所有存储库都已启用。
sudo add-apt-repository main
sudo add-apt-repository universe
sudo add-apt-repository multiverse
sudo add-apt-repository restricted
更新源并安装包。
sudo apt-get update
sudo apt-get install clamav clamtk
