我对命令输出中显示的Ign和的理解是那个和。Hitapt-get updateHit: File found. No change in its timestampIgn: File ignored. No change in its content.
Ign
Hit
apt-get update
Hit: File found. No change in its timestamp
Ign: File ignored. No change in its content.
这究竟是什么意思？例如，如果一个包要升级，是否意味着它的时间戳和它的内容一样改变了？
apt-get
apt-get ×1
