E Package Apache2 Has No Installation Candidate

Thinking that the problem lies with Ubuntu 20.04, I installed a copy of Ubuntu 18.04 and tried again. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'php-mcrypt' has no installation candidate E: Package 'libtime-modules-perl' has no installation candidate E: Package 'librrd4' has no installation candidate E: Package 'libpng12-0' has no installation candidate This may mean that the package is missing, has been obsoleted, or is only available from another source Package libpng12-0 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 Package librrd4 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: libtime-parsedate-perl Package php-mcrypt is not available, but is referred to by another package. Done Note, selecting 'php7.4-xml' instead of 'php-simplexml' Package libtime-modules-perl is not available, but is referred to by another package. Done Building dependency tree Reading state information. That command attempts to perform the install, but conks out early because packages cannot be found: Reading package lists. The prerequisites provided by the Server Requirements page for Ubuntu 16.06+ are as follows: $ sudo apt-get install mysql-server apache2 apache2-utils libapache2-mod-php openssh-client php php-ldap php-mbstring php-mcrypt php-mysql php-snmp php-simplexml nmap zip wget curl sshpass screen smbclient logrotate libtime-modules-perl ipmitool rrdtool librrd4 libpng12-0 So should this 'apt-get install' line be using mariadb-server?

I looked through all the other release notes from v3.3.2 up to v4.0.1, but don't see any mention of switching back to mysql-server. I also noticed that the release notes for OA v3.3.1 mention moving to mariadb-server for Ubuntu 20.04 instead of mysql-server, yet this 'apt-get install' line is still using mysql-server instead of mariadb-server. I am requesting that the documentation be updated to provide the correct prerequisite packages required for Ubuntu 20.04 LTS.Īt first I thought the best list of prerequisites would be in the ' How To Install or Upgrade Open-AudIT (Linux)' page (), but more recent prerequisite information is provided in the ' Server Requirements' page ().
