So, this is just to let people who see this message for a very long time when updating ISPConfig, wait a little longer. I found a lot of people who had aborted and tried to find the backup and reinstall, and sometimes it can take a while. I waited close to an hour and it finally worked. I ran the "top" command and gzip was going for about 30 min. before it worked. Anyway, thanks to the patient people who led me to believe it would finally go.
