Cannot update Manager

Post by wep_hkpu » Thu Aug 31, 2017 8:48 am

Dear lib-dev,

I'm trying to update the Manager System.
I have Internet connection to the device.
When I just clicked the button 'Install Updates', the text "Invalid file or file not found" suddenly appears although I haven't proceed to select any file, enter a URL, or click the 'Check for Updates' button.

I did try all of the 3 ways to update the Manager.
First, the Manager System refreshed when I clicked a) upload the local file or b) download from url.
Second, a message "Could not establish connection with server" appeared when I clicked 'Check for Updates' button.

I'm not quite sure whether it is about device's network interfaces.
I made some changes on the hostname below message appeared after restarted.
Back to factory presets

Warning: file(/etc/network/interfaces.default) [function.file]: failed to open stream: No such file or directory in /mnt/lib/var/www/ManagerSystem/core/API/parser_interfaces.php on line 20

Warning: Invalid argument supplied for foreach() in /mnt/lib/var/www/ManagerSystem/core/API/parser_interfaces.php on line 33
It seems to me that some files are missing.
Do you think I should perform the rescue process?

Regards.

Hi,

It looks like the networks interface file ("/etc/network/interfaces") is damaged for some reason or the system can not find it. The rescue process will solve the problem. If you want to do it, please fill the RMA form and our tech support team will contact you:

Dear lib-dev,

I did the rescue process once before.
I wonder whether I can use the same pen drive without building the new one.

Regards.
