I am going to install following package: gcc-4.9-aarch64-linux-gnu
But apt is unable to find it. I downloaded the .deb manually and installed it using dpkg. but there is some missing dependency. When I use apt to fix the problem it said:
$ sudo apt-get install gcc-4.9-aarch64-linux-gnu Reading package lists... Done Building dependency tree Reading state information... Done gcc-4.9-aarch64-linux-gnu is already the newest version (4.9.3-13ubuntu2cross1). You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies: gcc-4.9-aarch64-linux-gnu : Depends: cpp-4.9-aarch64-linux-gnu (= 4.9.3-13ubuntu2cross1) but it is not installable Depends: binutils-aarch64-linux-gnu (>= 2.26) Depends: gcc-4.9-aarch64-linux-gnu-base (= 4.9.3-13ubuntu2cross1) but it is not installable Depends: libgcc-4.9-dev-arm64-cross (= 4.9.3-13ubuntu2cross1) but it is not installable Depends: libmpfr4 (>= 3.1.3) but it is not installable Recommends: libc6-dev-arm64-cross (>= 2.13-0ubuntu6) but it is not going to be installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
What does it mean by
but it is not installable ? Why I can not install it? I have been added all 4 main repositories from Ubuntu. I am using ubuntu 18.04.
EDIT: I have seen this link. BUT I want to install it anyway. How I can? The problem with manual installation is its many dependency packages. Should I download and install all of them manually? Not less tedious way?!
