인터넷과 gpt에서 아래 파일을 수정하라고는 알려줬을 것 같다. 안했다면 확인해보기 

 

/etc/apt/sources.list 및 /etc/apt/sources.list.d/ 디렉터리 내의 파일들을 확인

 

sudo vi /etc/apt/sources.list

 

deb http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-backports main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse

 

그래도 해결이 안된다. 

 

그러면 아키텍쳐를 제거한다. 

 

1. 아키텍쳐 확인 

dpkg --print-architecture
dpkg --print-foreign-architectures

 

 

robo@DESKTOP-57PQH94:/etc/apt$ dpkg --print-architecture
-print-foreign-architectures
amd64
robo@DESKTOP-57PQH94:/etc/apt$ dpkg --print-foreign-architectures
armhf

 

 

 

robo@DESKTOP-57PQH94:/etc/apt$ dpkg --print-architecture
-print-foreign-architectures
amd64
robo@DESKTOP-57PQH94:/etc/apt$ dpkg --print-foreign-architectures
armhf
robo@DESKTOP-57PQH94:/etc/apt$ sudo dpkg --remove-architecture armhf
robo@DESKTOP-57PQH94:/etc/apt$ dpkg --print-foreign-architectures
robo@DESKTOP-57PQH94:/etc/apt$ dpkg --print-foreign-architectures
robo@DESKTOP-57PQH94:/etc/apt$ dpkg --print-architecture
