conda 更新后 Anaconda 中出现 PackagesNotFoundError

我最近在 Ubuntu 18.04 服务器上安装了 Anaconda，今天，当我安装一些新软件包时，出现了一个警告：

==> WARNING: A newer version of conda exists. <==
  current version: 4.6.14
  latest version: 4.7.5

Please update conda by running

    $ conda update -n base -c defaults conda

因此，我执行了上述命令（r_env如果重要的话，在我的环境中），一切似乎都很好：

(r_env) user@server:~$ conda update -n base -c defaults conda
Collecting package metadata: done
Solving environment: done

## Package Plan ##

  environment location: /home/user/anaconda3

  added / updated specs:

The following packages will be downloaded:

The following NEW packages will be INSTALLED:

The following packages will be UPDATED:

Proceed ([y]/n)? y

但是，此后我无法安装新软件包。它显示：

我尝试降级conda到 4.6.14，但没有成功 - 出现相同的错误。我可以在不重新安装 Anaconda 的情况下修复该问题吗？
