Update Akaunting to 2.0.15

Tried updating using the One-Click feature, but I get stuck at 20%.
Logging into my site using SSH as indicated in documentation to update manually, I get an error saying
Could not open input file: /public_html/account/artisan
doing an online search am seeing this means I have the wrong directory, funny enough, this is the actual directory of akaunting installation.

I am not sure what I missed, I would really appreciate any help.

Perhaps your file permssions are not correct

Ahmed same here. Also tried using ssh updater but says "Not able to get latest version of core"

James, My Files permissions seem to be alright, i will try reuploading latest files and linking to database, i don't know if that will work, worth a shot

Update: so i deleted my files in installation folder, and re uploaded latest files, i dd not have to relink it to the database. now it is updated to the latest version.
