Hi I’m trying to install erpnext using the manual located at Guide: Manual Install ERPNext on Ubuntu 17.xx & 18.xx .
While executing the command
sudo add-apt-repository 'deb [arch=amd64,i386,ppc64el] http://mirror.nodesdirect.com/mariadb/repo/10.2/ubuntu xenial main'
````Preformatted text`
I get an error `Preformatted text`sudo: unable to execute /usr/bin/add-apt-repository: Permission denied
Even If i proceed further ,
I get these errors :
While editing a configuration file
sudo nano /etc/mysql/my.cnf
I'm not able to edit the file , because the system never accept the changes .
Finally ,
When I pass these commands :
sudo systemctl restart mariadb
sudo systemctl enable mariadb
I get the an error :-
No D-B Connection , service manager
