我无法安装特定版本的 MySql 5.5。我正在使用本指南.当我尝试这个命令时
sudo apt-get 安装 mysql-server-5.5
输出为
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package mysql-server-5.5 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
However the following packages replace it:
percona-xtradb-cluster-server-5.5:i386 mysql-server-5.6:i386
mariadb-server-5.5:i386 percona-xtradb-cluster-server-5.5 mysql-server-5.6
mariadb-server-5.5 percona-xtradb-cluster-server-5.6:i386
percona-server-server-5.6:i386 mysql-testsuite-5.7:i386
mariadb-server-10.0:i386 percona-xtradb-cluster-server-5.6
percona-server-server-5.6 mysql-testsuite-5.7 mariadb-server-10.0
mysql-server-5.7:i386 mysql-server-5.7 mysql-common
E: Package 'mysql-server-5.5' has no installation candidate
我必须使用 Mysql-5.5。我尝试过其他方法，但没有得到任何肯定的结果。请帮忙。
