We are originally using Moodle 3.6.1 (2018120301), CentOS 7,4.1708, Apache 2.4.29, MySQL5.7.21, PHP 7.2.16, Theme- Essential 3.6.01 (201812704)

I am trying to upgrade it to Moodle 3.8.9.  I included the minimal necessary plugins that are previously installed, including upgrade version of Moove theme, plarigism - veriguide, lockdown browser, booktool wordimport.  However, it prompts the below error message after undergoing upgrade for several hours.

Warning: require_once(/usr/local/moodle/lib/navigationlib.pgp): failed to open stream: No such file or directory in /usr/local/moodle/lib/setup.php on line 599

Fatal error: require_once(): Failed opening required '/usr/local/moodle/lib/navigationlib.pgp' (include_path='/usr/local/moodle/lib/pear:.:/usr/local/php/lib/php') in /usr/local/moodle/lib/setup.php on line 599

It tried many times. The error message always occurs at the file under the directory /usr/local/moodle/lib/

Please let me know what is the cause of this error message. Kindly advise how to fix it. Thank you very much.

Essential theme no longer supported.   Suggest using a theme that comes with core code (boost) for the upgrade and beyond.

You could use config.php to set default theme:

$CFG->theme='boost';

Please see:

As I know "Essential" theme is no longer supported, I uninstalled this theme and select "boost" theme in advance. Make sure the Moodle 3.6 working well with boost theme. Then, I delete the "boost" theme code and put the "Moove" theme code into Moodle to perform the Moodle upgrade to version 3.8. Anyway, when I delete the "Essential" theme, it prompts an error message "core_plugin/err_removing_unremovable folder"

Should I simply add "$CFG->theme='boost'" into config.php instead of uninstalling the "essential" theme?

Actually, I tried the upgrade with different options of plugin. The final error messages are similar - "Fatal error: require_once(): Failed opening required'..." and are related to the file "/usr/local/moodle/lib/setup.php"

Please kindly advise. Thank you very much.

When you un-installed Essential theme how did you do that?

core_plugin/err_removing_unremovable folder??  Permissions on folders of code?

Fatal error: require_once(): Failed opening required '/usr/local/moodle/lib/navigationlib.pgp'

???? navigationlib.pgp?????

Did you look at line 559 of lib/setup.php?

Best to use core themes ... if not boost then classic.
Installing a new theme at the same time as upgrade very well could confuse things.

Are all your plugins compatible with the version you are upgrading to?

For more info, one could add the debugging lines from config-dist.php to config.php

I undergo the below steps to uninstall Essential theme.
1. Theme selector->Select "boost"
2. At Plugin overview->Theme->Essential->uninstall->It display SUCCESS.
3. Before clicking "Continue"->I delete the theme/essential folder in Linux
4. Click "Continue"->It prompts "core_plugin/err_removing_unremovable folder"
5. Then, I click "Upgrade Moodle database now"

The permission of code folder for directory is 755 and executable files are 644.

The below is a portion of setup.php. It looks like some PHP library file.
// Remember the default PHP timezone, we will need it later.
core_date::store_default_php_timezone();

// Load up standard libraries
require_once($CFG->libdir .'/filterlib.php'); // Functions for filtering test as it is output
require_once($CFG->libdir .'/ajax/ajaxlib.php'); // Functions for managing our use of JavaScript and YUI
require_once($CFG->libdir .'/weblib.php'); // Functions relating to HTTP and content
require_once($CFG->libdir .'/outputlib.php'); // Functions for generating output
require_once($CFG->libdir .'/navigationlib.php'); // Class for generating Navigation structure <----------"599"
require_once($CFG->libdir .'/dmllib.php'); // Database access
require_once($CFG->libdir .'/datalib.php'); // Legacy lib with a big-mix of functions.
require_once($CFG->libdir .'/accesslib.php'); // Access control functions
require_once($CFG->libdir .'/deprecatedlib.php'); // Deprecated functions included for backward compatibility

I will try to upgrade with Boost theme first and install Moove theme later. Thanks for advice.

I checked that all plugins are compatible to the version 3.8 I am upgrading except one plugin - Atto word import.
I had twice experience of successfully upgraded Moodle to 3.8 while I kept using the Atto word import 1.3.7 which is claimed to be compatible to Moodle 3.4 only. 

I tried to use Atto word import 1.4 which is compatible to Moodle 3.8, it popped up to request for the dependencies of Booktool word import. It is not allowed to install both of them because they own the same directory name "wordimport". If I only install the booktool one, the Moodle upgrade is also not successful.

I don't know what you mean by "I have installed the mod". Moodle and Wordpress are entirely separate applications, requiring their own space, database and so on.

There are tools to link them together. Search for 'Edwiser Bridge' for example.

Hi,

Our LMS has been upgraded to 3.11but the activity completion is not working.

I have ran through multiple courses and the progression within the SCORM acknowledges completion of the topics and SCORM package but the LMS will not recognise completion. After the upgrade some courses acknowledge completion, others do not, the settings for everything are exactly the same. Is anyone able to help please?

Have you contacted this to your hosting platform? I mean if a certain user has leverage from moodle hosting service or a managed hosting platform, don't you think their support team might take this issue?

Thanks for you fast response.

I finally fixed the issue and apparently it is working as a charm, but I'll monitor its behavior and move to another server if we have others issues in the future.

One more time, thank you for your collaboration in the forum and have a nice day.

First, for a CentOS 7 server, /usr/local/moodle is a strange location for moodle code.  CentOS 7 is Linux Standards Base distro which means apache config (httpd.conf) default would make /var/www/ apache users home directory.   In there, an html which is typically document root as defined in main config file for apache. /etc/httpd/conf/httpd.conf on typical setup.

Having moodle in /usr/local/ would mean there are or should be other config files that define that directory.   Do you have a special config file for that location or have you changed httpd.conf such that /usr/local/ is now apache home?

Plugin removal best done by Moodle Admin interface, but in the cases of plugins that have dependencies (require other plugins), one might have to resort to manually moving the plugin folders out to an archive directory, then visiting plugins via Moodle Admin interface ... it will say missing from disk ... that's ok, click the 'Upgrade Database' button and that should remove rows in mdl_config_plugins table that refer to those plugins.

In what you shared back about owner ... daemon,daemon????  The user for apache on CentOS 7 is typically 'apache' ... as defined in main config file /etc/httpd/conf/httpd.conf

A failed attempt to upgrade will mess with DB tables some so you might have to restore your DB to when site was running older version.

Hope you did a site backup ... code + DB minimally ... so you can restore and 'try it again'.

The next try, make sure you have debugging turned on from the get go.

What documents are you following for upgrading?

When your site was a 3.6, did you check server environment and update the component.   Then picked 3.8 as destination version to see if there were any reported issues concerning environment?

BTW, you never did answer the question about that strange file name ... ending with .pgp in moodle code related to navigation.   That's why I ask about what docs you are following for upgrading.

Dear All,

I cannot uninstall any plugin on my moodle installation.

Please assist?

Any advice would be appreciated

Am not a developer.   Best advice as a well-informed user/admin with many years experience ... don't delete core code - mod_lesson is one of those.  If you care not to use it, just hide it (deactivate it).

Sorry, I forgot to mention that it is just a UAT moodle site to test if upgrade is smooth.

Yes, it is a source code compile version of Apache. It is my Boss's habit that he always changes var/www/apache to /usr/local/moodle,

The user for apache on this CentOS 7 is daemone instead of 'apache' ... as defined in main config file /usr/local/apache2/conf/httpd.conf

After turn on the debugging mode, it shows the below error message:

Warning: array_key_exists() expects parameter 2 to be array, null given in /usr/local/moodle/lib/moodlelib.php on line 1499

Do you mean true compile?!!!!???
Like acquire source code then following directions from
this http://httpd.apache.org/docs/current/programs/configure.html#installationdirectories ?

What compile options were included for cache?

https://httpd.apache.org/docs/2.4/mod/mod_cache.html

What does:
/usr/sbin/httpd -V
return

Also:

 /usr/sbin/httpd -t -D DUMP_MODULES

Since your boss did it, he/she should know exactly how compiled ... including any switches options for PHP and supports for MySQL as well!

I used to compile the AMP stack for my servers.   Decided that it was just as good (less issues) to use the package manager of the OS and acquire stack that way.

Claudionir, which version of PHP have you downloaded? 32-bit or 64-bit? also Thread Safe or Non-Thread safe? ken has mentioned using 64-bit, and he's right not just in terms of memory limit, but PHP application performance as well. I had created a tutorial in past on 2012R2, but still applies on server 2019, you can have a look here. You may want to have a look at it before using it in production environment.
