无法在 conda 中安装或创建环境

每次我尝试安装软件包或创建环境时conda,都会出现如下消息:

Collecting package metadata (repodata.json): / DEBUG:urllib3.connectionpool:Starting new HTTPS connection (1): repo.anaconda.com:443

例如:

创建一个名为“env3”的环境:

conda create -n env3 -vv

出现:

要安装来自 的软件包conda,该消息会再次出现并且被冻结:

conda install -c conda-forge mamba

再次:

我已经尝试过:

  • 卸载并重新安装Anaconda,conda的版本是23.7.2.
  • 有几篇类似问题的帖子,例如:这个这个这个这个没有人为我工作。

我使用的是 Ubuntu 23.04。提前致谢。
