I am new in Linux and ubuntu. I'm trying to perform make in ubuntu terminal. But get an error: No hash found for gcc-7.4.0.tar.xz as in screenshot. GCC is installed, and the version is 7.5.0.
I'm trying to install gcc-7 to fix my problem, via sudo apt install gcc-7 g++-7, but get error that it is necessary to install some dependencies, more than 20 and I don't know how to do it. How I can fix this error? Thanks in advance.
