Linux系统下由于网络问题创建虚拟环境失败

报错内容如下：
Solving environment: failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url https://repo.anaconda.com/pkgs/free/linux-64/repodata.json.bz2
Elapsed: -

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.

If your current network has https://www.anaconda.com blocked, please file
a support request with your network engineering team.

SSLError(MaxRetryError(‘HTTPSConnectionPool(host=‘repo.anaconda.com’, port=443): Max retries exceeded with url: /pkgs/free/linux-64/repodata.json.bz2 (Caused by SSLError(SSLError(“bad handshake: Error([(‘SSL routines’, ‘ssl3_get_server_certificate’, ‘certificate verify failed’)])”)))’))

解决方法

1.首先是Linux系统，然后排除服务器不能联网的情况（可以ping www.baidu.com 看一下能不能接收结果）；
2. 我的config原配置是：

1）vim ~/.condarc
2）通过i 进入vim编辑模式，添加如下内容：

channels:
  - defaults
show_channel_urls: true
default_channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
custom_channels:
  conda-forge: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  msys2: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  bioconda: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  menpo: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  pytorch: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  simpleitk: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

3）通过 ESC + :wq 保存退出

----更新----
若按上文设置了condarc，创建新的conda环境出现下面报错：

Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  - python=3.11
  - libgcc-ng[version='>=11.2.0']
  - __glibc[version='>=2.17']

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

and use the search bar at the top of the page

同样的步骤：
1）vim ~/.condarc
2）通过i 进入vim编辑模式，设置为如下内容：

channels:
  - conda-forge
  - defaults
show_channel_urls: true
default_channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
custom_channels:
  conda-forge: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  msys2: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  bioconda: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  menpo: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  pytorch: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  simpleitk: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
