我正在與 Clamav 鬥爭，無論我做什麼，我都會收到錯誤
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
我試過
sudo apt-get -f install
sudo apt-get update
sudo apt-get upgrade
然後
sudo apt-get install clamav
然後
sudo apt-get install clamav clamtk
比從軟體中心，但沒有運氣。
有人可以幫我安裝 ClamAV 嗎？
答案1
確保所有儲存庫均已啟用。
sudo add-apt-repository main
sudo add-apt-repository universe
sudo add-apt-repository multiverse
sudo add-apt-repository restricted
更新來源並安裝軟體套件。
sudo apt-get update
sudo apt-get install clamav clamtk
