Cannot update to 3.0.0 and cannot create ticket

I tried creating a ticket, only to have the page refresh when I click on create.

Updating from within the UI has this message:

It is HIGHLY RECOMMENDED that files and database are backed up prior to applying this MAJOR update.

Update Akaunting to 3.0.0 version button is light blue and not clickable.

Updating manually using sudo php artisan update:all produces this error message:

Starting update...
Updating core...
The command php artisan update core 1 failed.

Exit Code: 1(General error)

Working directory: /var/www/akaunting

Output:
================

In Connection.php line 712:

could not find driver (SQL: select version() as mversion)


In Connector.php line 70:

could not find driver




Error Output:

Not able to update core!

Please advise. Thank you.

apt/yum install php-mysql php-pgsql

The same thing happening with me while updating from version 2.1.36 to 3.0.1

No luck, unfortunately. After updating and installing the suggested

apt install php-mysql php-pgsql

Then entering the same install command

sudo php artisan update:all

Here's the results:

Starting update...
Updating core...
The command php artisan update core 1 failed.

Exit Code: 1(General error)
