Upgrading mysql on Ubuntu Lucid Lynx (10.04) hangs

Wed, 28 Nov 2012 00:00:00 +0000

Already the third time this happens to me: An update is available for the mysql server and I just “apt-get upgrade”. The upgrade process gets totally stuck at the following task:Preparing to replace mysql-server-5.1 5.1.66-0ubuntu0.10.04.1 (using …/mysql-server-5.1_5.1.66-0ubuntu0.10.04.2_i386.deb) …mysql stop/waitingThe process that got again stuck in some eternal loop (or whatever) is an egrep replacement of some textfile:egrep -qi -r ^[^#]*ndb.connectstring|^[:space:]*\[[:space:]*ndb_mgmd /etc/mysql/I just killed that process and the upgrade resumes as nothing would have happened.

After installing the Suse 9 rpm, execute the following commands:sudo /usr/bin/mysql_install_db(Creating default databases & permissions. Apparently the same can be done by “sudo rcmysql start”)sudo /usr/bin/mysqld_safe --user=mysql &(Start the server for the first time)REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! This is done with: /usr/bin/mysqladmin -u root password 'new-password' /usr/bin/mysqladmin -u root -h hostname password 'new-password'Give all privileges to root and user:/usr/bin/mysql -u root -p Enter password:Welcome to the MySQL monitor.
