我经常尝试安装软件包，但由于文件被锁定而无法安装unattended-upgrades。通常，安装过程要运行 6 个小时以上。
这正常吗？
鉴于我有
$ cat /etc/apt/apt.conf.d/20auto-upgrades
APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "1";
$ cat /etc/apt/apt.conf.d/10periodic
APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "0";
APT::Periodic::AutocleanInterval "0";
我想这是出乎意料的。
PS：我现在已按照更改了配置这。希望它能够缓解这个问题。
编辑＃1：这可能表明它实际上正在等待（由于网络问题。很可能是由于代理阻塞）并重试，同时保持锁定。我猜在等待的同时保持锁定是非常不幸的。

至于其他问题，我还没有找到原因，但我已经更新libpython2.7并libpython2.7-dev查看这是否可以消除一些重试和延迟。
$ sudo apt-get install libpython2.7
...
The following additional packages will be installed:
libpython2.7-dev libpython2.7-minimal libpython2.7-stdlib python2.7 python2.7-dev python2.7-minimal

在快速测试中，我无法获得网络速度，但这通常不是问题
