在 Ubuntu 20.04.1 上安装 libssl-dev（从 18.04.1 升级）报告 1.1.1g-1+ubuntu18.04.1+deb.sury.org+1 存在未满足的依赖关系

我已经从 Ubuntu 18.04.1 升级到 Ubuntu 20.04.1（强制发布升级），然后在安装时还php.7-4需要安装libssl-dev，这导致了以下未满足的依赖项：

sudo apt install libssl-dev
The following packages have unmet dependencies:
 libssl-dev : Depends: libssl1.1 (= 1.1.1f-1ubuntu2) but 1.1.1g-1+ubuntu18.04.1+deb.sury.org+1 is to be installed

  • 我已禁用存储库：ondrej和certbot。其余存储库是 focal fossa (20.04.1) 的默认存储库

  • 清理存储库，例如（apt update --fix-missing）

但问题仍然存在。

问题在于需要降级的 libssl1.1 (= 1.1.1f-1ubuntu2) 的字母版本。使用以下命令可轻松完成此操作，synaptic而不是apt install如下操作：

sudo aptitude install libssl-dev

he following NEW packages will be installed:
  libssl-dev{b} 
0 packages upgraded, 1 newly installed, 0 to remove and 0 not upgraded.
Need to get 1.582 kB of archives. After unpacking 8.005 kB will be used.
The following packages have unmet dependencies:
 libssl-dev : Depends: libssl1.1 (= 1.1.1f-1ubuntu2) but 1.1.1g-1+ubuntu18.04.1+deb.sury.org+1 is installed
The following actions will resolve these dependencies:

     Keep the following packages at their current version:
1)     libssl-dev [Not Installed]

The following packages will be DOWNGRADED:
  libssl1.1 
The following NEW packages will be installed:
  libssl-dev 
0 packages upgraded, 1 newly installed, 1 downgraded, 0 to remove and 0 not upgraded.
Need to get 2.900 kB of archives. After unpacking 8.087 kB will be used.
Do you want to continue? [Y/n/?] Y

基本上不接受建议的解决方案并进行软件包降级

我只是这样做，并且对我有用:)

sudo apt-get install libssl1.1="1.1.1f-1ubuntu2"
