Ubuntu更新-换源问题
docker学习过程中,可以使用更新镜像再commit以及build Dockerfile的方式提交镜像,再apt-get update命令执行过程中,报错connection timed out Could not connect to archive.ubuntu.com:80 (185.125.190.36)
通过帖子(Linux 云服务器 sudo apt-get update Cannot initiate the connection to archive.ubuntu.com:80_柴华松的博客-CSDN博客)知道,需要更新ubuntu源,替换aliyun的源之后,仍然报错NO_PUBKEY:
尝试去安装gpg提供密钥信息,无果;转一下思路,有没有不需要密钥的ubuntu源呢,发现以下163的源可以,推荐大家使用:
deb http://mirrors.163.com/ubuntu/ focal main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ focal-security main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ focal-updates main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ focal-proposed main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ focal-proposed main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ focal-backports main restricted universe multiverse
替换之后重新执行apt-get update,可以看到问题解决:
还没有评论,来说两句吧...
