试图看看这个链接是否可以帮助我。
我跑了：sudo apachectl -t得到了syntax ok。我无法运行sudo apache2 -X -f /etc/apache2/httpd.conf，因为我没有httpd.conf文件。如果我跑：service apachectl start我得到Failed to start apachectl.service: Unit apachectl.service not found.
这是我的/etc/apache2/envvars
# envvars - default environment variables for apache2ctl
# this won't be correct after changing uid
unset HOME
# for supporting multiple apache2 instances
if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else

# Since there is no sane way to get the parsed apache2 config in scripts, some
# settings are defined via environment variables and then used in apache2ctl,
# /etc/init.d/apache2, /etc/logrotate.d/apache2, etc.

## The locale used by some modules like mod_dav
export LANG=C
## Uncomment the following line to use the system default locale instead:

export LANG
## The command to get the status for 'apache2ctl status'.
## Some packages providing 'www-browser' need '--dump' instead of '-dump'.
#export APACHE_LYNX='www-browser -dump'
## If you need a higher file descriptor limit, uncomment and adjust the
## following line (default is 8192):
#APACHE_ULIMIT_MAX_FILES='ulimit -n 65536'
## If you would like to pass arguments to the web server, add them below
## to the APACHE_ARGUMENTS environment.
#export APACHE_ARGUMENTS=''
## Enable the debug mode for maintainer scripts.
## This will produce a verbose output on package installations of web server modules and web application
## installations which interact with Apache

任何有关如何再次访问我的网站的帮助将不胜感激。我可以通过 WinSCP 和 Putty 进行 SSH 访问。
我在联想笔记本电脑上有 Kubuntu 18.10 和 KDE Plasma 5.14.4。
是否有 CPU 监视器小部件以 GHz 显示 CPU 频率？
我想要以 GHz 为单位从系统托盘中的小部件进行实时监控。
如果可能，如何使 Psensor 以 GHz 或类似的方式显示 CPU 频率？
我想从系统托盘监视 CPU 频率（以 GHz 为单位），并且不想像副本那样以百分比监视 CPU 使用率。
我有带有 KDE Plasma 环境的 Ubuntu 18.10。
安装新程序时：
首先它安装程序，然后我收到此消息：
2018/10/30 14:18:34.231310 main.go:150: description of advise-snap's
"from-apt" is lowercase: "advise-snap vil tale med apt via en apt-hook"
“vil tale med”是丹麦语，意思是“想要交谈/联系”。
在网上找不到任何东西。
任何解决此问题的帮助将不胜感激，谢谢！
联想ideapad 320。
我更愿意通过 GUI 解决此问题，但也可以接受来自终端的修复。
xinput --list --short
我有罗技 USB 接收器
xinput --set-prop "Logitech USB Receiver" "Device Accel Constant Deceleration" 1.5
Warning: There are multiple devices matching 'Logitech USB Receiver'.
To ensure the correct one is selected, please use the device ID, or prefix the
device name with 'pointer:' or 'keyboard:' as appropriate.
“id9”的正确代码是什么？还是图形用户界面修复？
谢谢
