I'm trying to update from v1.92 to current (2.05). In my admin panel it shows there's an update available, and says "You can update manually or do the 3-click ComfortUpdate". When I click on 3-click ComfortUpdate, I get:
Error : PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature
Zlib is showing as on in my phpinfo. Is there anything else I should check that might be causing this error? I saw one other forum message with this error, and they said they just kept refreshing until it worked. I've tried that a number of times, however, and it just keeps coming up with the same error. (I've also seen a number of references for other software updates giving this message that suggest low disk space can be a culprit, but there is a large amount remaining on this server.)
As an update - based on some other searching, I tried disabling mod_security as a test. Still the same error message. It's able to connect to the update server from what I can tell - if I check for updates it seems to work just fine.
