[root@localhost ~]# conda install samtools Solving environment: failed CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/linux-64/repodata.json> 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. ConnectionError(ReadTimeoutError("HTTPSConnectionPool(host='mirrors.tuna.tsinghua.edu.cn', port=443): Read timed out.")) 之前配置清華鏡像如下：
[root@localhost bin]# conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ [root@localhost bin]# conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ [root@localhost bin]# conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/ [root@localhost bin]# conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/ [root@localhost bin]# conda config --set show_channel_urls yes [root@localhost bin]# conda config --get channels 后來修改.condarc文件（vi /root/.condarc），刪除所有鏡像，只添加這兩個鏡像。
[root@localhost ~]# cat /root/.condarc channels: - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/ show_channel_urls: true 下載成功了：
