ubuntu 8.04下安装最新版本的lazarus

1、设置ubuntu到能够上网

2、在终端中运行下面的命令获得一个网站PGP的Key
gpg –keyserver hkp://pgp.mit.edu:11371 –recv-keys 3A5B1204

3、添加Key到系统中
gpg –export 3A5B1204 | sudo apt-key add -

4、修改ubuntu更新源：
sudo gedit /etc/apt/sources.list

内容设置如下（这里请注意最下面一行，这个就是Lazarus的老窝）：
deb hardy main restricted universe multiverse
deb hardy-security main restricted universe multiverse
deb hardy-updates main restricted universe multiverse
deb hardy-proposed main restricted universe multiverse
deb hardy-backports main restricted universe multiverse
deb-src hardy main restricted universe multiverse
deb-src hardy-security main restricted universe multiverse
deb-src hardy-updates main restricted universe multiverse
deb-src hardy-proposed main restricted universe multiverse
deb-src hardy-backports main restricted universe multiverse
deb lazarus-testing universe

5、更新系统：
sudo apt-get update

6、到新立得里面搜索lazarus，安装，注意不要选择它上面的那个fpc-src，因为这个fpc-src版本老，安装lazarus的时候，会自动装上最新的版本。
