| Certificate verification failed: The certificate is NOT trusted. No system certificates available. Try installing ca-certificates. |

具体如图

系统环境是ubuntu:22.04 ARM架构

二、解决方法

1、先不要更换镜像源 直接设置

apt update
apt -y install ca-certificates

2、更换镜像源

vim /etc/apt/sources.list

清华镜像源内容如下

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy main restricted universe multiverse

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy-security main restricted universe multiverse
