Fatma's questions

This problem: "Some results have been removed because Restricted Mode is enabled by your network administrator." and "This video is restricted. Try signing in with a G Suite account."

I am using ubuntu 18.04.4 lts. I encounter this error on youtube in all browsers. I'm sure the restricted mode is off but sometimes it happens sometimes not, so it doesn't always happen, but I couldn't understand what it's about. Besides, the error continues whether or not I am logged in. I cannot view many videos on youtube without using vpn. Windows is also installed on my computer, there is no such problem. ***I'm deleting this question a third time and asking again, is there really anyone to help?

I am using 18.04.4 lts version of Ubuntu. I downloaded Code::Blocks from "Ubuntu Software" and didn't install any other package. I do not know if the packages required for development are installed. This error:

||=== Build: Debug in Hello (compiler: GNU GCC Compiler) ===|
 obj/Debug/main.o||No such file or directory|
||error: no input files|
||=== Build failed: 2 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

Codeblocks installation I tried this but it didn't work. I'm new on Ubuntu, can you help?
