嗯,Ubuntu 20.04 官方源安装系统后,SSH登入后会提示:
New release '22.04.3 LTS' available.
Run 'do-release-upgrade' to upgrade to it.
如何隐藏这个提示呢?
方法如下:
cat <<EOF > /etc/update-motd.d/91-release-upgrade
#!/bin/sh
# if the current release is under development there won't be a new one
if [ "\$(lsb_release -sd | cut -d' ' -f4)" = "(development" ]; then
exit 0
fi
# if it is non-root user, skip
if [ $(id -u) -ne 0 ]; then
exit 0
fi
#if [ -x /usr/lib/ubuntu-release-upgrader/release-upgrade-motd ]; then
# exec /usr/lib/ubuntu-release-upgrader/release-upgrade-motd
#fi
EOF
其实就是注释掉了/etc/update-motd.d/91-release-upgrade最后3行代码。
或者干脆:
chmod -x /etc/update-motd.d/91-release-upgrade
