Fix Unable to detect release version (use '--releasever' to specify release version)

rpm -ivh https://mirror01.idc.hinet.net/CentOS/8-stream/BaseOS/x86_64/os/Packages/centos-gpg-keys-8-6.el8.noarch.rpm
rpm -ivh https://mirror01.idc.hinet.net/CentOS/8-stream/BaseOS/x86_64/os/Packages/centos-stream-repos-8-6.el8.noarch.rpm
rpm -ivh https://mirror01.idc.hinet.net/CentOS/8-stream/BaseOS/x86_64/os/Packages/centos-stream-release-8.6-1.el8.noarch.rpm

會遇到這個問題是在 migrate to Rocky Linux 時中斷造成
再次執行 migrate2rocky.sh 腳本會出現錯誤

Found a full or partial RockyLinux install already in place. Aborting
because continuing with the migration could cause further damage to system.

修改 migrate2rocky.sh 把出現上面訊息的 if 那一段拿掉，上面的 rpm 補完，再執行一次就可以了

SSH via Shadowsocks

Local address: 127.0.0.1
Local port: 1080
Server IP: 12.34.56.78

~/.ssh/config 加入

Host *

ProxyCommand connect-proxy -S 127.0.0.1:1080 %h %p

若要 ssh 到 Server IP，改用 ssh 127.0.0.1
