Не могу установить phpmyadmin и mysql

после прерванного обновления сервера LTS Ubuntu 10.04 до сервера LTS Ubuntu 12.04 некоторые компоненты были установлены неправильно. В любом случае я установил apache, ftp, phpmyadmin и т. Д. В какой-то момент я удалил некоторые пакеты, которые вызывали проблемы и которые испортили мою установку mysql и phpmyadmin. Теперь я не могу установить mysql и phpmyadmmin. Я получаю следующую ошибку при попытке установить mysql:

The following packages have unmet dependencies:
mysql-server-5.1 : Depends: mysql-client-5.1 (>= 5.1.67-0ubuntu0.10.04.1) but it is not      going to be installed
E: Unable to correct problems, you have held broken packages.

И получаю следующую ошибку при попытке установить phpmyadmin:

Reading package lists... Done

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libxml-libxml-perl : Depends: perl (>= 5.14.2-6ubuntu1) but it is not going to be installed
Depends: libxml-namespacesupport-perl but it is not going to be installed
libxml-sax-expat-perl : Depends: perl but it is not going to be installed
Depends: libxml-namespacesupport-perl (>= 0.03) but it is not going to be installed

libxml-sax-perl : Depends: perl but it is not going to be installed
Depends: libxml-namespacesupport-perl but it is not going to be installed
Depends: libxml-sax-base-perl but it is not installable
phpmyadmin : Depends: perl but it is not going to be installed
Recommends: apache2 or lighttpd but it is not going to be installed or                 httpd
Recommends: mysql-client
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
