Question Error in upgrading from k 1.5 to k1.7 (see attached screen shot)

I received this error when installing k1.7 on my k1.5 installation. However, as near as I can tell with just a few, quick tests, K1.7 is installed and seems to be operating correctly.

Hello,

1°) You server SQL is very slow, so sometimes the queries fails
2°) I need to check it by myself

Download and Upgrage to 1.6 and then make it 1.7 ...try this might work..

The site is a test site, so you are welcome to take a look - temp.ceoexpert.net. If you want backend access, I can send you a password (but I need to do it via email). today or tomorrow, I will try "Radioactive's" suggestion of going to k1.6 and then k1.7

To clarify "Radioactive's" post, I initially missed his/her point, but to re-enforce my situation, I was upgrading from K1.6.4 to k1.7.0. The Joomla version is j1.5.23, so I was already upgrading from k1.6 !

Here is the configuration information before the attempted upgrade:

Try to make the upgrade again, but when there should be no traffic in your site.

xillibit was slightly wrong: MySQL server has gone away usually means that timeout in MySQL is very short (few seconds). The issue is that Joomla first connects to database and then starts to unzip files, which is very slow operation. This takes, say 10 seconds, and when done, Joomla tries to contact database to update information. It fails because of MySQL thinks that the connection was left open and should be closed.

The error is potentially very dangerous as it's likely that some important database updates during installation fails. Kunena avoids these traps by reloading the page after file copies, but Joomla doesn't do it. The only real solution is to increase MySQL timeout so that installer has enough time to copy all the files. Or you can try by trial and error, hoping that your site will stay alive after each upgrade -- Kunena or something else like CommunityBuilder..
