I'm trying to install xdebug on Ubuntu:
sudo apt-get install php-xdebug
and getting following error:
Need to get 806 kB of archives. After this operation, 4.423 kB of additional disk space will be used. Err:1 http://ppa.launchpad.net/ondrej/php/ubuntu artful/main amd64 php-xdebug amd64 2.5.5-3+ubuntu17.10.1+deb.sury.org+1 404 Not Found E: Failed to fetch http://ppa.launchpad.net/ondrej/php/ubuntu/pool/main/x/xdebug/php-xdebug_2.5.5-3+ubuntu17.10.1+deb.sury.org+1_amd64.deb 404 Not Found E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
How can I solve this problem ?
First, you need to update local packages using the following command:
sudo apt update
# OR
sudo apt-get update
Now you can install xdebug with the following command:
sudo apt install php-xdebug
And configure it as:
sudo nano /etc/php/{YOUR_PHP_VERSION}/mods-available/xdebug.ini
Add the following code into it:
zend_extension=/usr/lib/php/20151012/xdebug.so
xdebug.remote_autostart = 1
xdebug.remote_enable = 1
xdebug.remote_handler = dbgp
xdebug.remote_host = 127.0.0.1
xdebug.remote_log = /tmp/xdebug_remote.log
xdebug.remote_mode = req
xdebug.remote_port = 9005 #if you want to change the port you can change
Note: Directory 20151012 is most likely to be different for you. cd into /usr/lib/php and check which directory in this format has the xdebug.so file inside it and use that path.
And then restart the services:
sudo systemctl restart php7.0-fpm
sudo systemctl restart nginx # If you are using nginx server
sudo systemctl restart apache2 # If you are using apache server
UPDATE 2024/01/11: In Xdebug3 you have to set the following xdebug.ini
zend_extension=xdebug.so
xdebug.start_with_request = yes
xdebug.mode = debug
xdebug.remote_handler = dbgp
xdebug.client_host = 127.0.0.1
xdebug.log = /tmp/xdebug_remote.log
xdebug.client_port = 9005 #if you want to change the port you can change
