4.7.8 linux update issue

Java is already 9.0.4… I just tried the same I always did when updating, following the instructions on command line… I get this error below. Trying to update from 4.7.7 to 4.7.8.

A problem occurred while detecting installed or update versions - update cannot continue.

Please submit a support ticket @Roberto Trevisan. We need to view more of your files to determine what’s triggering this error. Thanks.

Hi, my company partner @Lauro Dorneles has already opened a support ticket, can we keep his ticket, which has all the files zipped and all the information about the environment system. Is that ok?


Hello Lauro,

Thank you for emailing Wowza Technical Support! Your support request, # (338043), has been received and placed into our Standard Support queue.



Oh sure thing, that is fine. Let me check it and follow the conversation.

It appears that they are requesting more info and that Lauro is providing that info. Hopefully, a solution is close and thank you for submitting the ticket.

I am happy I choose to reinstall as this update was more of an upgrade than an update.
