谢谢大佬江湖救急!

master@X16:~$ cat /etc/apt/sources.list
bash: master@X16:$：未找到命令
把下面的复制替换 /etc/apt/sources.list，然后设置中心检查更新失败，请教具体如何操作呢？是不是第一步就不对？谢谢！

cat << EOF |sudo tee /etc/apt/sources.list
deb https://community-packages.deepin.com/beige/ beige main commercial community
#deb-src https://community-packages.deepin.com/beige/ beige main commercial community
EOF

复制全部内容到终端执行

master@X16:~$ cat /etc/apt/sources.list

bash: deb：未找到命令

谢谢，试过会报上面这个错误啊

看其他帖子

sudo apt update && sudo apt dist-upgrade -y

然后删除 Generated by deepin-installer，控制中心检查也没更新了，好像是搞定了

六个#号和一个#号试过好像还是不行，不过加#号控制中心检查更新时不报错了，不知道刚才另一条命令sudo apt update && sudo apt dist-upgrade -y成功没，先就这样吧，您费心了，多谢！

beige前面加上deepin，否则以后会出问题，因为官方软件源地址正在更换。https://bbs.deepin.org/post/261181
