我被這個問題困擾了：-
# apt-get install software-properties-common

E: Unable to locate package software-properties-common
有人可以告訴我如何解決這個問題嗎？
這是 apt-cache 策略的輸出

答案1
您的儲存庫配置不包括 Debian 9 儲存庫（安全儲存庫除外）；你需要確保你/etc/apt/sources.list至少包含
deb http://deb.debian.org/debian stretch main
deb http://deb.debian.org/debian stretch-updates main
deb http://security.debian.org stretch/updates main
答案2
自從軟體包software-properties-common肯定存在於 Debian 9 中，問題一定出在您正在使用的儲存庫鏡像中。
嘗試使用不同的儲存庫。
