Hi all, I’m trying to install Percona 5.5 on an Ubuntu 12.04 LTS and I get this error: root@test:/etc/apt# apt-get install percona-server-server-5.5 percona-server-client-5.5 Reading package lists… Done Building dependency tree Reading state information… Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: percona-server-client-5.5 : Depends: libdbi-perl but it is not installable percona-server-server-5.5 : Depends: libdbi-perl but it is not installable Depends: libdbd-mysql-perl but it is not installable Depends: libaio1 (\>= 0.3.93) but it is not installable E: Unable to correct problems, you have held broken packages. I googled this and found a bug issue dating 2013 that supposed to be fixed but nothing recent. Any help will be appreciated. Thanks, Serge ---

Hi, Serge; I just tried this on a clean 12.04LTS install and it went off without a hitch. Here’s the sum total of what I did - maybe you missed a step, possibly the apt-get update? root@localhost:~# history 1 apt-key adv --keyserver [keys.gnupg.net](http://keys.gnupg.net) --recv-keys 1C4CBDCDCD2EFD2A 2 vim /etc/apt/sources.list \*Here I added: #percona deb [URL][http://repo.percona.com/apt[/URL]](http://repo.percona.com/apt%5B/URL%5D) precise main deb-src [URL][http://repo.percona.com/apt[/URL]](http://repo.percona.com/apt%5B/URL%5D) precise main 3 time apt-get update 4 time apt-get install percona-server-server-5.5 percona-server-client-5.5 5 mysql 6 mysql -e “CREATE FUNCTION fnv1a\_64 RETURNS INTEGER SONAME ‘libfnv1a\_udf.so’” 7 mysql -e “CREATE FUNCTION fnv\_64 RETURNS INTEGER SONAME ‘libfnv\_udf.so’” 8 mysql -e “CREATE FUNCTION murmur\_hash RETURNS INTEGER SONAME ‘libmurmur\_udf.so’” 9 mysql 10 history root@localhost:~# To double-check, I went ahead & removed the relevant packages & then reinstalled, and it worked fine. I suspect if you try the following sequence, you’ll get the same result: dpkg --remove percona-server-client-5.5 dpkg --remove libdbi-perl libdbd-mysql-perl dpkg --remove percona-server-common-5.5 libperconaserverclient18 dpkg --remove percona-server-server-5.5 dpkg --purge percona-server-server-5.5 apt-get install percona-server-server-5.5 percona-server-client-5.5
