i'm using ubuntu v18.4 with apache2 and php7.3.3 installed. I tried to install php-debug in vscode, but i always get this error when start debugging:

Cannot evaluate code without a connection

here's my configuration:

/etc/php/7.3/mods-available/xdebug.ini

zend_extension=xdebug.so
xdebug.remote_autostart=1
xdebug.remote_log=/var/log/apache2/xdebug.log
xdebug.default_enable = 1
xdebug.remote_enable=1
xdebug.remote_port=9000

launch.json

{ 
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Listen for XDebug",
            "type": "php",
            "request": "launch",
            "port": 9000
        },
        {
            "name": "Launch currently open script",
            "type": "php",
            "request": "launch",
            "program": "${file}",
            "cwd": "${fileDirname}",
            "port": 9000
        }
    ]
}

i'm using ubuntu 18.04 and i tried to install dnscrypt using this tutorial

but when i tried to connect to a website it always failed, i tried to check the status of the dnscrypt service, and it shows error [ERROR] Unable to retrieve server certificates like this:

i tried to edit /etc/resolv.conf and change the nameserver to 127.0.2.1 but when i restarted the NetworkManager, the nameserver goes back to 127.0.0.53

after that i tried to disable these two, but nothing changes

sudo systemctl disable dnscrypt-proxy.service && sudo systemctl disable dnscrypt-proxy-resolvconf.service

I'm using ubuntu 18.04, I tried to move the 'show applications' from right to left in my dock using this command in terminal:

gsettings set org.gnome.shell.extensions.dash-to-dock show-apps-at-top true

but when I checked the dock, the show applications icon still appears at the right side
