将.Net Core 1.0升级到2.0 Ubuntu 16.10

Question

我正在尝试将.net核心版本从1.0升级到2.0，但出现一些错误。 我不擅长Linux，所以我不太了解发生了什么。

我跑：

apt-get install dotnet-sdk-2.1.4

我得到这个错误：

Reading package lists... Done

Reading state information... Done

所以，我尝试安装dotnet-runtime-2.0.5 ，我得到了

Reading package lists... Done

Reading state information... Done

此后，我尝试安装libicu55但我已经安装了libicu57 。 我不知道该怎么办。

is only available from another source

你有什么想法？

因此，全新安装Ubuntu 16.04的确是……尽管有一个陷阱，您可以选择是否选择LTS（长期支持）。 我选择不这样做，因为它是VM，而且我不介意较新的更新，等等……事实证明，安装.NET Core并不是一个好主意！ 看来，一旦安装了非LTS，您最终会得到16.10，该版本已安装了一些较新版本的必需库，即称为libicu的库，它现在是57，而不是必需的55。

尝试在计算机上手动安装libicu55（它应与计算机上的较新版本并排运行）：

1. 从此处下载文件： http : //packages.ubuntu.com/en/xenial/amd64/libicu55/download
2. 使用以下sudo dpkg –i libicu55_55.1-7_amd64.deb安装它： sudo dpkg –i libicu55_55.1-7_amd64.deb
