Upgrading Drupal

After updating from 6.15 to 6.16 I'm getting this error in a lot of pages:

user warning: Table 'xviisinfo.drupal_semaphore' doesn't exist query: SELECT expire, value FROM drupal_semaphore WHERE name = 'locale_cache_pt-pt' in /home/sinfo/public_html/XVII/includes/lock.inc on line 154.

I have a feeling it has to do with the new "locking framework for long running operations"
http://drupal.org/node/251792

How to : install security update 6.16 on 6.15?

I tried updating my 6.14 to 6.15 now I get this error "Fatal error: Call to undefined function user_access() in /home/alanaime/public_html/includes/menu.inc on line 2476". I used the upgrade provided by my host.

Any help is appreciated.

I am moving my site to a new server, where I will upgrade it from D5 to D6.

I have heard of problems with D6 supporting PHP 5.3. After a certain version of Drupal core, these problems supposedly had been remedied.

I follow someone on twitter who specifically posted that problems still remained with contributed modules, but didn't specify.

Is there any major reason to go with PHP5.3 over 5.2.13?

Otherwise, I'm inclined to go with 5.2.13.

Any thoughts?

Hi,

Could some one please help me here. I tried to update my site from 5.2 to latest 6.x version. And I see the following result at the end. Please point me the link if there is any patch for this. And also I am not able to login as site admin as well because it always prompts me "site is in offline mode". I don't know how to fix this?

Drupal database update
user warning: Duplicate key name 'type_name' query: ALTER TABLE system ADD INDEX type_name (type(12), name) in /home/paradesi/public_html/includes/database.mysql-common.inc on line 434.
user warning: Duplicate key name 'pid' query: ALTER TABLE comments ADD INDEX pid (pid) in /home/paradesi/public_html/includes/database.mysql-common.inc on line 434.
Updates were attempted. If you see no failures below, you may proceed happily to the administration pages. Otherwise, you may need to update your database manually. All errors have been logged.

Reminder: don't forget to set the $update_free_access value in your settings.php file back to FALSE.

Hi!

I have two languages enabled. I'm using i18n to manage the languages. After I upgraded to d6 see the following:

1) All existing terms with defined aliases in default language have the aliases as expected
2) All existing terms with defined aliases in another language have only system aliases like taxonomy/term/ID and could not be changed!

Also, see many "empty" system terms that look like "taxonomy/term/", (no ID). These empty terms have different aliases that look like "taxonomy/term/ID" (with ID)

Any ideas?
