解决Conda安装软件兼容性问题的发现与失败：UnsatisfiableError

相关环境

lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 20.04.4 LTS
Release:	20.04
Codename:	focal

python -V
Python 3.9.13

which python
/home/user/miniconda3/bin/python

conda --version
conda 22.9.0

通过conda 在base环境中安装特定的程序
conda install -c bioconda A程序

报错如下

检查并尝试修改对应环境下的
libgcc_s.so; libgcc_s.so.1文件的权限，没有效果。

受到一些解决类似的问题的文章的提示，尝试对conda更新以解决兼容性问题
conda update –all
conda update conda
但都没有效果。
有些文章建议使用conda install -c conda-forge A程序 ；但是提示没有找到对应的程序

在另一个服务器相同的环境下执行
conda install -c bioconda A程序
成功安装，没有报错。
查看两个服务器区别，尤其是conda相关的配置
通过conda config –show查看镜像
成功安装的服务器的conda配置了一些国内的镜像，而报错的服务器是使用的原始镜像。问题可能找到；
在报错的服务器添加国内镜像
conda config –add channels https://mirrors.bfsu.edu.cn/anaconda/cloud/conda-forge/
conda config –add channels https://mirrors.bfsu.edu.cn/anaconda/pkgs/main/
conda config –add channels https://mirrors.bfsu.edu.cn/anaconda/pkgs/free/
conda config –add channels https://mirrors.bfsu.edu.cn/anaconda/cloud/bioconda/
conda config –add channels http://mirrors.aliyun.com/anaconda/cloud/bioconda/
conda config –add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/main/
conda config –add channels https://mirrors.ustc.edu.cn/anaconda/cloud/conda-forge/
conda config –add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
再进行安装，成功。
