Dear Support,

Upgrading from v26 to v27 ubuntu server 22.04. Have all requirements satisfied sql 10.6.18 and php 8.1.2.

ssh into server /var/www/Gibbon then:

# sudo wget /GibbonEdu/core/releases/download/v27.0.01/GibbonEduCore-InstallBundle.zip \*\*forum does not allow posting links

# sudo unzip GibbonEduCore-InstallBundle.zip

At this stage answer “A” to replace all. also tried with “N” to replace none. The later does nothing the former results in below.

# sudo chown www-data:www-data /var/www/Gibbon -R

also restart apache2 and log through GUI + presented with update screen.

However when pressing the “submit” button to update database from v26.0.00 to v27.0.01 get a “file not found” screen.

Any assistance is greatly appreciated.

Thanks

Any help is greatly appreciated… System is unusable.

Hi @pllabreu and @globalgen

This appears to be a bug in a recent version of Apache, please see this post for more info: ['File Not Found' Error in Gibbon V26 and Gibbon V27 - #3 by MissBee](https://ask.gibbonedu.org/t/file-not-found-error-in-gibbon-v26-and-gibbon-v27/9092/3)
