WordPress MU

The automatic update worked fine in my dev environment going from 2.7.1 to 2.8.1. I just tried going from 2.8.1 to 2.8.2 and I got:

Downloading update from http://mu.wordpress.org/wordpress-mu-2.8.2.zip.

Unpacking the update.

Could not copy files.

Installation Failed

I'm not particularly worried, but I just thought people would like to know.

Same type of Error. Auto-Install Fails for me as well. Disappointing, after the complications with the last upgrade...

"Could not copy files."

Usually means it can't copy the files because of folder permissions.

I agree, Andrea, but can you imagine why it would work for 2.7.1 => 2.8.1 but not for 2.8.1 => 2.8.2?

Is it possible the upgrade to 2.8.1 actually restricted some folder permissions and as result, is preventing the upgrade to 2.8.2?

jshare, seeing the same thing here and am as confused as you are.

Could be last time some permissions were set back.

I have the same problem. Clean upgrade to 2.8.1 but now get:

Warning: copy(/SERVERPATH/html/wp-content/upgrade/wordpress-mu-2.8.2/wordpress/wp-admin/includes/update-core.php) [function.copy]: failed to open stream: No such file or directory in /SERVERPATH/html/wp-admin/includes/class-wp-filesystem-direct.php on line 131

Could not copy files.

Any ideas?

Thanks

Yep, I've got the same problem.

Downloading update from http://mu.wordpress.org/wordpress-mu-2.8.2.zip.

Unpacking the update.

Warning: copy(/home/accountname/domain.com/wp-content/upgrade/wordpress-mu-2.8.2/wordpress/wp-admin/includes/update-core.php) [function.copy]: failed to open stream: No such file or directory in /home/accountname/domain.com/wp-admin/includes/class-wp-filesystem-direct.php on line 131

Could not copy files.

Installation Failed

Performed a manual upgrade and tried forcing a re-update and received the message everyone is getting.

Anyone have the same?

I updated my local install via the zip file and all is well, but I'm a bit paranoid now about updating my live site... (and my connection is too slow to try a manual upload.)

"(and my connection is too slow to try a manual upload.) "

Tip: upload the zip to the server and unpack it there. FTPing one large file is faster (in the long run) than many smaller files.

Same problem here as well.

Same bug again. Had the EXACT same one as my upgrade from 2.8 > 2.8.1. Something about not being able to copy, update-core.php. Previous solution which worked for 2.8.1 was to update two files as advised on the bug report thread, 'functions.php' and 'wp-functions.php' and it worked.

Still stuck now. Wordpress MU Dev Team, please advise ASAP. Thanks :)

Manually upgrade. :)

I had the same problem, manual upgrade was successful.

Does anyone know the minimum amount of files and folders I can upload to perform a complete manual upgrade? I would like to overwrite the smallest amount of files possible to complete this.

you can go to trac (http://trac.mu.wordpress.org) and do a diff between revisions. That will show you exactly the files that have changed, and it provides a zip file at the bottom.

Browse the branches to get the revision numbers.

This ticket has been created on trac, we now await some news on how to upgrade automatically without problems.

In /wp-admin/includes/class-wp-upgrader.php

Change:
// Copy update-core.php from the new version into place.
if ( !$wp_filesystem->copy($working_dir . '/wordpress/wp-admin/includes/update-core.php', $wp_dir . 'wp-admin/includes/update-core.php', true) ) {

To:
// Copy update-core.php from the new version into place.
if ( !$wp_filesystem->copy($working_dir . '/wordpress-mu/wp-admin/includes/update-core.php', $wp_dir . 'wp-admin/includes/update-core.php', true) ) {

Automatic upgrade should then work correctly.

Worked! Thanks!

@Albertane, did this, but no go... Any further suggestions? Manually updated one of my installations to 2.8.3 and the problem persists. Thanks very much!

If it is a permissions issue, which folders should I check and what should their settings be?

@Albertane Thanks - your solution works fine.

@albertane never mind my question, your fix worked! thanks!

Nice one Albertane!

@Albertane many, many thanks. Automatic upgrade worked perfectly after your fix.

:-)

@Albertane - Worked for me as well on wpmu 2.8.2 -> 2.8.3 automatic upgrade. However, the first time around, I still received the error even after editing the class-wp-upgrader.php file. So, I logged out, cleared the browser cache, and logged back in. After which, the change seemed to take, and the upgrade was about 10 secs.

FYI- if you don't use Alberane's fix, the automatic upgrade still doesn't work:

Downloading update from http://mu.wordpress.org/wordpress-mu-2.8.3.zip.

Unpacking the update.

Could not copy files.

Installation Failed

This was an automatic upgrade attempt from 2.8.1.

Hi Albertine,
Worked beautifully thankyou so much!

Hi Albertane,

Your fix is still working for wordpress-mu-2.8.4a.zip.

Thanks
