我从 OVH 租用了一台没有 Plesk 许可证的 VPS，但他们还是在未经我同意的情况下安装了 Plesk。这导致了很多问题。我做每件事都费劲，安装最新版本的 Python 3，拥有正确版本mod_wsgi或升级到 Debian Buster...
现在，我想从 Apache 迁移到 Nginx，但情况很乱。我以为首先我必须自己安装 Nginx，但由于 Plesk，它已经安装好了。我想删除它，但我的apt命令陷入了一种难以解决的相互依赖问题。
当我做：
apt-get remove nginx
结果：
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libnginx-mod-http-auth-pam : Depends: nginx-common (= 1.14.2-2+deb10u1) but it is not going to be installed
libnginx-mod-http-dav-ext : Depends: nginx-common (= 1.14.2-2+deb10u1) but it is not going to be installed
libnginx-mod-http-echo : Depends: nginx-common (= 1.14.2-2+deb10u1) but it is not going to be installed
libnginx-mod-http-geoip : Depends: nginx-common (= 1.14.2-2+deb10u1) but it is not going to be installed
libnginx-mod-http-image-filter : Depends: nginx-common (= 1.14.2-2+deb10u1) but it is not going to be installed
libnginx-mod-http-subs-filter : Depends: nginx-common (= 1.14.2-2+deb10u1) but it is not going to be installed
libnginx-mod-http-upstream-fair : Depends: nginx-common (= 1.14.2-2+deb10u1) but it is not going to be installed
libnginx-mod-http-xslt-filter : Depends: nginx-common (= 1.14.2-2+deb10u1) but it is not going to be installed
libnginx-mod-mail : Depends: nginx-common (= 1.14.2-2+deb10u1) but it is not going to be installed
libnginx-mod-stream : Depends: nginx-common (= 1.14.2-2+deb10u1) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
如果我尝试
apt --fix-broken install
结果：
...

结果相同sudo apt-get install -f nginx-common nginx-full
注意：
ls /etc/default/nginx
ls: cannot access '/etc/default/nginx': No such file or directory
因为我移动了它，所以没有什么可以覆盖 :/
我尝试使用以下命令删除这些包：
sudo apt-get remove libnginx* --purge
它给：
Package 'libnginx-mod-http-cache-purge' is not installed, so not removed
Package 'libnginx-mod-http-fancyindex' is not installed, so not removed
Package 'libnginx-mod-http-headers-more-filter' is not installed, so not removed
Package 'libnginx-mod-http-lua' is not installed, so not removed
Package 'libnginx-mod-http-ndk' is not installed, so not removed
Package 'libnginx-mod-http-perl' is not installed, so not removed
Package 'libnginx-mod-http-uploadprogress' is not installed, so not removed
Package 'libnginx-mod-nchan' is not installed, so not removed
Package 'libnginx-mod-rtmp' is not installed, so not removed
sudo apt-get autoremove nginx给出了相同的结果。我真的被这个问题困扰了。
dpkg -l | grep "libnginx-mod-http-cache-purge"不返回任何内容。
如果我进行搜索，/var/lib/dpkg/status我也找不到那些包。
我也跑：
dpkg --configure -a
但它会导致以下类型的错误：
...
dpkg: error processing package libnginx-mod-http-echo (--configure):
dependency problems - leaving unconfigured
dpkg: dependency problems prevent configuration of libnginx-mod-http-subs-filter:
libnginx-mod-http-subs-filter depends on nginx-common (= 1.14.2-2+deb10u1); however:
Package nginx-common is not installed
...
我想要一个干净的 Nginx 安装，我原来的安装已经损坏，我希望能够随时轻松更新它。我该怎么办？
