Hello.

I'm running Odoo 11 community edition on Debian 10.

Recently I discovered that a Windows computer where I download backup from Odoo server, started to download damaged backup zip file. When I download backup from Odoo server from a Debian computer, the backup zip file is OK. I don't know yet reason, why Windows computer is downloading damaged Odoo backup zip file - this started couple of days ago, maybe afrer last Windows update. I tried browsers Chrome and Firefox.

Now the problem. I uploaded one damaged Odoo backup zip file to a Debian 10 based Odoo server. After that, the server is responding from serverip/web/database/manager

"Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application."

I understand that damaged zip file is causing this behavior, Odoo can't unzip the file.

How to solve this? How to interrupt the damaged zipfile process and get back the normal 

"serverip/web/database/manager" window where I could upload correct Odoo zipfile?

Thank you in advance.
