Up to yesterday, linkage to Dropbox was working fine. i.e. whenever I update the programs, Dropbox icon shows busy sign temporarily, and indidates an update message following that. I found this morning that any change to a program does not get reflected to Dropbox any more. This problem could have caused by my careless shut down of my PC: Last night, I shut down the PC closing the terminal emulator window of the VM windows. Error messages came out at that time, but I didn't pay much attention. The picture below shows the bottom right corner of the current screen. This could be the cause but I do not know how to fix it.
The 169.254.4.95 IP address does not match to any of the IP address of VMBox network. I have dobblechecked both the IPv4 adapter and DHCP Server's (I'm not sure which it should match to). I would appreciate it very much if anyone could give me a hint to solve this problem.
