Upgrading Drupal

I've noticed a couple of posts where people have reported upgrading and/or installing modules where they get a message like "Update failed! See the log below for more information" and there is no log! I just tried updating the wysiwyg module and got a failure stating that the file transfer failed, because it "cannot remove directory ..." It then states "Your modules have been downloaded and updated" as if nothing was wrong. I have got some kind of error message like this pretty well every time I have attempted an install or update of a module.

Ok I am a total nube to this subject but not a Drupal nube. If I create a site in Drupal 6 will it be easy in the future for me to migrate over to Drupal 7 without losing any content or messing up the database?

If this is easy to do, how do you do it?

Hey everyone...I'm still getting my head around LAMP and Drupal.

I had a Drupal 6.19 site on an Ubuntu 8.04 distro (VPS) and decided to move to Debian. So I setup a Debian 5 VPS, MySQL, Apache2, PHP 5.2.x. Then did the following:

1) Created a new database
2) Installed Drupal 6.19
3) Used Backup and Migrate on the old site
4) Copied over my sites folder
5) Imported the old database

I have read about Editarea, codeMirror, Colorer etc. but not sure how to get any of it working on drupal 6.19

I want it for HTML and PHP mostly

SQL query:

-- -- Dumping data for table `cache_views` -- INSERT INTO `cache_views` (`cid`, `data`, `expire`, `created`, `headers`) VALUES ('views_tables:en', 0x613a343a7b733a363a227461 [...]

MySQL said: Documentation
#1153 - Got a packet bigger than 'max_allowed_packet' bytes 

Hi, I am getting around to upgrading a D5 site to D6 - (don't ask) but when i try to import the DB into MAMP/PHPMyAdmin I get this message.

So can i trim the table in some way?

I recently tried to upgrade my drupal website with the latest modules: filefield, ctools, and panel by copying all the files of the modules to my existing module directories. After all the modules are updated, I immediately lost my connection to my website and all subsequent login attempts yielded the "HTTP 500 Internal Server Error". I now regretted that I didn't disable the panel/ctools/filefield related configuration before I performed the update.... Any help to restore my website will be appreciated....
