#509 Automatic update fails while compressing archive with error ... has invalid extension ...

[Oliver Heil]

The automatic update procedure fails while compressing the backup archive with error:

data phar "/var/www/nocc-1.9.8/nocc-1.9.8_backup_20191115181102.9.8_backup_20191115181102.tar.gz" has invalid extension 9.8_backup_20191115181102.tar.gz

This happened after upgrading php5 to php7.

Workaround:

Edit file update.php line 319:

Old line:

$archive->compress(Phar::GZ,substr($archive_name,strpos($archive_name,'.')+1).".gz");

to new line:

$archive->compress(Phar::GZ);

And try the automatic update again.
