什么是“sudo apt-get clean”？

Question

当我收到软件更新消息并单击安装时，我收到一条消息“空间不足”，告诉我清空垃圾箱并使用sudo apt-get clean. 我已经清空了垃圾箱，但仍然收到相同的消息，并且不知道要删除哪些临时文件或删除哪些临时文件sudo apt-get clean。

Answer 1

sudo apt-get clean清除检索到的包文件的本地存储库。它从/var/cache/apt/archives/和/var/cache/apt/archives/partial/.

来源 ： man apt-get

查看使用该命令时会发生什么的另一种可能性是使用-optionsudo apt-get clean模拟执行-s。

mook@MookPC:~$ apt-get -s clean
注意：这只是一个模拟！
      apt-get 需要 root 权限才能真正执行。
      还请记住，锁定已停用，
      所以不要依赖于与真实当前情况的相关性！
Del /var/cache/apt/archives/* /var/cache/apt/archives/partial/*
Del /var/lib/apt/lists/partial/*
Del /var/cache/apt/pkgcache.bin /var/cache/apt/srcpkgcache.bin

mook@MookPC:~$ sudo apt-get -s clean

Del /var/cache/apt/archives/* /var/cache/apt/archives/partial/*
Del /var/lib/apt/lists/partial/*
Del /var/cache/apt/pkgcache.bin /var/cache/apt/srcpkgcache.bin

如果您收到消息“空间不足”并且命令sudo apt-get clean不足，请尝试以下操作：

打开终端，

按Ctrl+ Alt+T

运行：

sudo -i   # (Allows you to execute commands with the privileges of the superuser.)       

KERNELCUR=$(uname -r | sed 's/-*[a-z]//g' | sed 's/-386//g')
PKGLINUX="linux-(image|headers|ubuntu-modules|restricted-modules)"
METAPKGLINUX="linux-(image|headers|restricted-modules)-(generic|i386|server|common|rt|xen)"
KERNELSOLD=$(dpkg -l | awk '{print $2}' | grep -E "$PKGLINUX" | grep -vE "$METAPKGLINUX" | grep -v "$KERNELCUR")

apt-get purge "$KERNELSOLD"   # (Remove old kernels.)

CONFOLD=$(dpkg -l | grep '^rc' | awk '{print $2}')  

apt-get purge "$CONFOLD"   # (Removes configuration files from deb packages that have been uninstalled.)
apt-get autoremove   # (Deletes orphaned packages, or dependencies that remain installed after you have installed an application and then deleted it.)
apt-get clean   # (Removes all packets from the cache.)
rm -rf /home/*/.local/share/Trash/*/** &> /dev/null   # (Empty the trash from all users.)
rm -rf /root/.local/share/Trash/*/** &> /dev/null   # (Empty the trash from root.)
