Update 5.5 error

[louis55]

Hi
I'm updating the site from 5.4 to 5.5, following the usual step-by-step process from 1 to 7.
But unable to update this time, when clicking "Extensions/Check for updates",
"Invalid response from EDC server!"

Then I clicking "Elxis update" under "Extensions/Check file-system",
new window pop-up and display the step of "1/7:Download Elxis" page.
When I click "1/7:Download Elxis" the following message display;
"CURL is required in your PHP installation inorder to download Elxis!"

Please advise and thanks advance.

Hello,
Please contact with your web hosting company and inform them enable: CURL in your PHP installation.

Do as Webgift told you, enable CURL in your PHP installation.

However, if this is not possible do the following:

Go to elxis.org and download Elxis 5.5 zip package.
Rename this zip file to elxis.zip
Upload elxis.zip inside this folder: {repository}/tmp/

Run Elxis update again. Elxis will use elxis.zip file found inside your repository folder without downloading it from elxis.org.
So, you bypass the problem.

If you need Elxis 5.5 hashes (for files checking) you will find them here:
https://www.elxis.org/update/hashes4/elxis_hashes_5.5.txt
Download it and upload it in your site here:
{repository}/cache/edc/elxis_hashes_5.5.txt
