How to install "not installable" dependancies?

I'm trying to install Codelite on Ubuntu Artful (17.10). I've seen this problem is very common online but I haven't found a fix. Basically when I run sudo apt-get install codelite wxcrafter I get these unmet dependancies

Reading package lists... Done Building dependency tree Reading state information... Done 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: codelite : Depends: libclang1-3.6 (>= 3.2) but it is not installable Depends: libhunspell-1.3-0 (>= 1.3.3) but it is not installable Depends: liblldb-3.6 but it is not installable Recommends: lldb (>= 3.4) but it is not going to be installed Recommends: nodejs but it is not going to be installed E: Unable to correct problems, you have held broken packages. 

Now I've tried to manually install Artful versions of the dependancies (such as ) but the error remains there. I'm kind of a noob on these sort of things. Is there anyway to like manually install a dependancy? (from like a downloaded file?) Or is there any sort of fix to this?

Thank you very much!
