1. 问题:使用conda update更新conda后anaconda所有环境崩溃 (系统的base没有崩溃) 系统ubuntu18.04 1.1 问题描述 在创建的虚拟环境中安装包时提示更新conda WARNING: A newer version of conda exists. current version: 22.9.0latest version: 23.1.0Please update conda by running\( conda update -n base -c defaults conda我更新后报错如下 Preparing transaction: done Verifying transaction: done Executing transaction: done Retrieving notices: ...working... failed
