Then I follow the answer of (Ubuntu 14.04) apt-get libopencv-dev, but get errors: Unable to correct problems, you have held broken packages
And I can not install libgtk2.0-dev. I get the problem of installing libgtk2.0-dev:The following packages have unmet dependencies:

Any suggestions? This is freaking me out! I have googled mant times. But there isn't a solution.Thanks a lot!
Did you try to "apt-get update && apt-get upgrade" ??
If you have broken packages, you can use "apt-get install -f"
-f, --fix-broken
Fix. Attempt to correct a system with broken dependencies in place. This option, when used with install/remove, can omit any packages to permit APT to deduce a likely solution. Any package(s) that are specified must completely correct the problem. This option is sometimes necessary when running APT for the first time; APT itself does not allow broken package dependencies to exist on a system. It is possible that a system's dependency structure can be so corrupt as to require manual intervention. Use of this option together with -m may produce an error in some situations.

These missing dependencies were selected when I compiled the firmware
Why is that
I tried self-compiling the firmware, adding all the missing dependencies, repackaging, and reburning the firmware, but still got an error: missing dependencies
What is your kernel version? Are you in the same version as 5.10.107?
Also, did you try to download that ipk and manually install it? If you are sure that you did enable it at the kernel level, there is no harm in trying to install it with force overriding. Or you could run the binary directly to see if there is an error.
If you really need to make it works, you can always try to cross-compile this package for your kernel.
which version your openwrt? I suggest using apfree-wifidog cause wifidog not maintained for years

I keep getting unmet dependencies problem while installing docker and cant find a relevant solution to it. Screenshot of problem
Installing rmagick on Ubuntu
there are solutions for different versions of ubuntu, but none worked on 17.04 ?
sudo apt-get install libmagickwand-dev gives

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libmagickwand-dev : Depends: imagemagick-6-common (= 8:6.9.7.4+dfsg-3ubuntu1) but 8:6.9.7.4+dfsg-3ubuntu1.2 is to be installed
Depends: libmagickwand-6.q16-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Couldn't find any solution for this. Updated to Ubuntu to 17.10, where it works fine.
You can search for any packages in ubuntu doing a sudo apt-cache search libmagickwand-dev and if you find the package you are looking for then install it doing sudo apt-get install libmagickwand-dev,
Installing all the unmet dependencies should fix the problem, and it is always helpful to do the commands below to upgrade any missing packages
sudo apt-get upgrade && sudo apt-get update
You should be able to install rmagick without any issues after this.

Electric relies on different versions of core libraries. Although this question is about hydro. The same issue applies to you.
ROS depends on specific versions of system libraries such as Boost, and the versions of those libraries that are available on 12.04 and 14.04 are different enough to make installing the 12.04 binaries on 14.04 very difficult.
If the ROS version doesn't matter, ubuntu 14 binaries work for indigo and up
Edit
There is a thread of someone building electric to work on 12.04 here, but there's a bunch of custom configuration that needs to happen to build it.
