Não consigo instalar a versão específica do MySQL 5.5. Estou usando o guia . Quando estou tentando este comando
sudo apt-get install mysql-server-5.5
A saída é
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
É obrigatório que eu use o Mysql-5.5. Eu tentei outros, mas não obtive nenhum resultado afirmativo. Por favor ajude.
