Error showing while uploading theme in wordpress

Question

I have tried to install a wordpress theme using upload option in wordpress. However when I upload it the following error message is showing.

The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Invalid archive structure

Please help with the possible solutions.

Thanks in advance

Answer 1

That sounds like the zip file you are uploading either isn't a zip file or is corrupt.

Try re-downloading the theme from the source and then try uploading again.

Answer 2

I had same issue on php 7.2 |ubuntu 18.04 | wordpress 5.2, then I install php7.2-zip using apt install php7.2-zip according to some research but it didn't fix theme update issue from back-end. Then I installed php curl using sudo apt-get install php7.2-curl and that fix the issue.

php curl for ubuntu:

• PHP 7.2: sudo apt-get install php7.2-curl
• PHP 7.1: sudo apt-get install php7.1-curl
• PHP 7.0: sudo apt-get install php7.0-curl
• PHP 5.6: sudo apt-get install php5.6-curl
• PHP 5.5: sudo apt-get install php5.5-curl
• If you don't know your php version: sudo apt-get install php-curl
