snap在debian11下好像出啥问题了：cannot change profile for the next exec call: No such file or directory
内核是kernel5.10，使用snap安装的certbot会提示：
cannot change profile for the next exec call: No such file or directory
检查了链接都没问题，目测可能是兼容性问题，已经把脚本换到用pip安装了。
解决办法：
apparmor_parser --add /var/lib/snapd/apparmor/profiles/snap.certbot.*CertBot运行语句改写为：
snap refresh core && apparmor_parser --add /var/lib/snapd/apparmor/profiles/snap.certbot.* && certbot --nginx --no-redirect --register-unsafely-without-email想了想还是修一下吧，运行一下诊断模式：
