Error Unable To Decompress File When Upgrading From 4.1.5 To 4.2.1

Dear all,



I'm trying to update from 4.1.5 to 4.2.1 but failed. The errors shown are:



[color=#B94A48]Unable to decompress file[/color]

[color=#B94A48]Failed to extract files from the archive[/color]



The following folders and its subfolders already set as 777: var, images, design

I have the exact same problem. Anyone know how to fix this?

Anyone?

Just a guess since there isn't much info to go off of but see if Zip is installed.

anyone solve this?

tried var folder with 755 and 777 permissions

zip is installed

upgrading from 4.1.3 to 4.1.4

It seems that the issue is caused by a bug in PHP. Try to downgrade your PHP version and check the results.

Thanks, it works ok in php 5.3.29 but not in 5.6.21

anyone know how i can just modify the file, so i don't have to downgrade first.

Looks like the error is coming from the fn_decompress_files function in the file fn.fs.php, in the PharData extractTo method
