我無法在我的電腦上安裝 ncurses 庫。當我使用 make 編譯它時，出現致命錯誤 n.curses.h: No such file or directory。
我嘗試透過終端安裝它，但沒有成功。我收到這樣的回覆：sudo apt-get install libncurses5 libncurses5:i386
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libncurses5
E: Unable to locate package libncurses5:i386
我還嘗試修復我的 source.list ，因為我使用了：
sudo tee /etc/apt/sources.list
但是，它刪除了文件中的所有內容。在網上搜尋我發現了這個：
deb http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal-backports main restricted universe multiverse
（...）
複製並貼上到我的 source.list 上，並將 ' #' 放在顯示deb或 的位置deb-src。現在，我無法透過終端下載任何軟體，你能幫我嗎？

所以您正在執行 64 位元 Ubuntu 20.04 LTS。您可以使用以下單一長命令恢復預設 APT 儲存庫：
cat <<EOF | sudo tee /etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu/ focal main universe multiverse restricted
deb http://security.ubuntu.com/ubuntu/ focal-security main universe multiverse restricted
deb http://archive.ubuntu.com/ubuntu/ focal-updates main universe multiverse restricted
deb http://archive.ubuntu.com/ubuntu/ focal-backports main universe multiverse restricted
deb-src http://archive.ubuntu.com/ubuntu/ focal main universe multiverse restricted
deb-src http://security.ubuntu.com/ubuntu/ focal-security main universe multiverse restricted
deb-src http://archive.ubuntu.com/ubuntu/ focal-updates main universe multiverse restricted
deb-src http://archive.ubuntu.com/ubuntu/ focal-backports main universe multiverse restricted
EOF
增加 32 位元 i386 架構，使用更新軟體包清單並安裝所需的軟體包
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libncurses5 libncurses5:i386
