You might want to run 'apt --fix-broken install' to correct these.

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
I also have tried the following solutions but they did not work.

I spend a day searching for a solution on how to access the ReadySHARE printer on NETGEAR R7000 router but I cannot found out the solution. It works well on windows 10 and Mac with the software provided by NETGEAR. Also, the printer works when I directly connect the printer to my ubuntu computer.
Router
Router Model : NETGEAR R7000
Firmware Version : v1.0.7.2_1.1.93
Router IP : 192.168.1.1
Printer Server IP : Don't see any IP on router setting webpage for connecting the printer
Connection with Printer : USB
Printer
Printer : Fuji Xerox DocuPrint P205 b
I can find my printer under the Network Printer
.
But after the configuration, I cannot print a test page.

Is it unsolvable currently?

I want to remotely login a Ubuntu Router via OpenSSH but when I type the following to login, I cannot get back any response from the Ubuntu Router in the command line.
ssh [email protected]
- Login the Ubuntu Router via SSH from a host behind the Ubuntu Router ⇒ Fail
- Login the Ubuntu Router via SSH from a host outside the router private network
192.168.1.0
⇒ Fail
IPs of the Ubuntu Router
# External
IP Address: XXX.XXX.XXX.XXX
# Internal
IP Address: 192.168.1.1
Testing
Then, I tried the followings to test.
- Login the Ubuntu Router via SSH in the Ubuntu Router itself ⇒ Success
- Ping
XXX.XXX.XXX.XXX
from a host behind the Ubuntu Router ⇒ Success - Ping
192.168.1.1
from a host behind the Ubuntu Router ⇒ Success - Ping
8.8.8.8
from a host behind the Ubuntu Router ⇒ Success - Ping
XXX.XXX.XXX.XXX
from a host outside the router private network192.168.1.0
⇒ Success
Therefore, I concluded that the package can reach the Ubuntu Router but it cannot trigger the SSH response for requesting password for login. After tried the following command to unblock port 22 by the iptables (1), the problem still not solved.
iptables -A OUTPUT -p tcp --sport 22 -j ACCEPT

After reading this article, I carry on the installation but it does not work. This is the properties page:
I have attempted to print test page but the status shows me "Processing - Not connected?". The following are the screenshots.
If I just directly use the wire to connect the printer, it works. [usb://FUJI%20XEROX/DocuPrint%20P205%20b?serial=WKK-850460]
I have also tried:

ipp14://192.168.0.1:631/lp1
No one works.
This is the status of my router.
Could you teach me how to configure the setting?
Thank you for your attention.

1. When I set to others instead of 1440x900 (16:10) or 1280x800 (16:10) revolutions,
the black bar must disappear.
2. When I set to 1440x900 revolution, the black bar must exist.
The display area is not fit to my monitor(1440x900) and there is a black bar at the top of my screen. The bottom of the display area can't be displayed. How can I deal with this problem?
I wonder if the problem come from the lack of display card (MSI R4770 Cyclone) driver but I don't know how to install it. Do I need to install it?
