=== For Ubuntu 14.04 and Debian 7.0 ===
+
First, as the root user install all the dependencies for EPrints ('''N.B.''' Some dependencies may not be able in certain versions of Debian/Ubuntu. See [[#Operating System Version Specific Requirements|Operating System Version Specific Requirements]] towards the end of this page):
−
As the root user create a file at /etc/apt/sources.list.d/eprints.list and add the following line

Now to install EPrints and all its dependencies execute the following command, again as the root user:
+
If you are installing on Ubuntu, install MySQL server and client:
  
−
apt-get update
+
  apt install mysql-server mysql-client libmysqlclient-dev
−

−
At present the latest Deb for EPrints (3.3.15) is not signed, therefore you will not to accept that it is unauthenticated.  The next Deb package release of EPrints (3.3.16) should be signed.

=== For Ubuntu 16.04 and Debian 8 ===
+
Next, create the eprints user
−
The current Debian package (Deb) for EPrints 3.3.15 will not install on Ubuntu 16.04 and Debian 8 due to unmet dependencies, as certain other Deb packages have been removed between versions.  The Deb for the next version of EPrints (3.3.16) will have amended dependencies, so the same method for Ubuntu 14.04 and Debian 7.0 can be used.
 
  
−
Instead of setting up the deb.eprints.org package repository download this [http://files.eprints.org/1712/1/eprints_3.3.15_all-xenial.deb modified version of the 3.3.15 Deb package] and run the following command as root from the same directory as you downloaded it:
+
adduser eprints
  
−
apt-get install ./eprints_3.3.15_all-xenial.deb
+
Now add the eprints user to the www-data group and vice-versa

First, as theroot users install all the dependencies for EPrints:
+
apt install git
 +
mkdir /opt/eprints3
 +
chown eprints:eprints /opt/eprints3
 +
chmod 2775 /opt/eprints3
 +
su eprints

 +
tar -xzvf eprints-3.4.6.tar.gz
  
−
useradd eprints
+
Then put in the source code in place:
  
−
Next, clone the Git repository from GitHub to /opt/ and set the eprints user as the owner.  It is probably best to checkout the latest release rather than using HEAD, which may have known issues:
+
mv eprints-3.4.6 /opt/eprints3
 +
chmod 2775 /opt/eprints3
 +
chown -R eprints:eprints /opt/eprints3
  
−

If you want a publications flavoured repository, then also:
−
git clone https://github.com/eprints/eprints.git /opt/eprints3
 
−
cd /opt/eprints3/
 
−
git checkout tags/v3.3.15
 
−
chown -R eprints:eprints .
 
  
−
Next, as the eprints user copy /opt/eprints3/perl_lib/EPrints/SystemSettings.pm.tmpl to /opt/eprints3/perl_lib/EPrints/SystemSettings.pm
+
wget https://files.eprints.org/3097/6/eprints-3.4.6-flavours.tar.gz
 +
tar -xzvf eprints-3.4.6-flavours.tar.gz

chown -R eprints:eprints /opt/eprints3/flavours/pub_lib
  
−
EPrints is now fully installed at /opt/eprints3. However, you will not yet have a running archive. Follow the [[Getting Started with EPrints 3]] instructions to set this up.

 +
Next, as the eprints user copy <code>EPRINTS_PATH/perl_lib/EPrints/SystemSettings.pm.tmpl</code> to <code>EPRINTS_PATH/perl_lib/EPrints/SystemSettings.pm</code>, if it does not already exist.
  
−
Now, update Apache configuration to set it up to use the eprints user and group, by ensuring the following lines are set thus in /etc/apache2/envvars:

=== Installing LibXSLT.so from CPAN ===
 
−
There are some issues with the LibXSLT.so that is installed by the Deb package libxml-libxslt-perl, which causes the Apache webserver to generate a segmentation fault.  libxml-libxslt-perl will be removed as a dependency from the next eprints Deb package (3.3.16) but is you want to integrate EPrints with third party applications (e.g. Symplectic Elements) then you will need this installed.  A version that does not suffer this segmentation fault can be installed using CPAN.
 
−
 
 
−
First, as root install the following Deb packages:
 
−
 
 
−
apt-get install build essential libxslt1-dev zlib1g-dev libgdbm-dev
 
  
−
Then, again as root install the YAML module for CPAN.   
+
You should now be able to access your vanilla repository at the hostname you specified when running '''epadmin create''' from the [[Getting Started with EPrints 3]] instructions.  You should then login as the admin user you created during this process and turn on the indexer.  This can be done by clicking on the '''Admin''' link under the Logged in menu, then clicking on the '''System Tools''' tab and finally the '''Start Indexer''' button.

Requirements

  • Ubuntu 22.04 LTS and Ubuntu 24.04 LTS (non-LTS versions not recommended)
  • Debian 11 (Bullseye) or Debian 12 (Bookworm) - These are not as comprehensively tested as Ubuntu LTS versions.

Dependencies and Pre-configuration

The ideal way to install from source is via git using the Core Git repositories EPrints 3.4 or EPrints 3.3, and installing from a source tarball is generally discouraged.

Installing from source via git is now the recommended way to install EPrints for production repositories, after having proved to be a useful installation method to those seeking to develop the EPrints code, develop a plugin or develop a Bazaar package too.

First, as the root user install all the dependencies for EPrints (N.B. Some dependencies may not be able in certain versions of Debian/Ubuntu. See Operating System Version Specific Requirements towards the end of this page): 

apt install perl libncurses5 libselinux1 apache2 libapache2-mod-perl2 libxml-libxml-perl \
  libunicode-string-perl libterm-readkey-perl libmime-lite-perl libmime-types-perl libdigest-sha-perl \
  libdbd-mysql-perl libxml-parser-perl libxml2-dev libxml-twig-perl libarchive-any-perl libjson-perl \
  liblwp-protocol-https-perl libtext-unidecode-perl lynx wget ghostscript poppler-utils antiword elinks \
  texlive-base texlive-binaries psutils imagemagick adduser tar gzip unzip libsearch-xapian-perl \
  libtex-encode-perl libio-string-perl python3-html2text make libexpat1-dev libxslt1-dev

If you are installing on Ubuntu, install MySQL server and client: 

 apt install mysql-server mysql-client libmysqlclient-dev

If you are installing on Debian, install MariaDB server and client: 

 apt install mariadb-server mariadb-client libmariadb-dev

Next, create the eprints user 

adduser eprints

Now add the eprints user to the www-data group and vice-versa 

usermod -a -G eprints www-data
usermod -a -G www-data eprints

Downloading and Deploying EPrints Source

EPrints 3.4.x for GitHub

apt install git
mkdir /opt/eprints3
chown eprints:eprints /opt/eprints3
chmod 2775 /opt/eprints3
su eprints
git clone https://github.com/eprints/eprints3.4.git /opt/eprints3
cd /opt/eprints3/
git checkout tags/v3.4.6

EPrints 3.4.x from files.eprints.org

cd /tmp/
wget https://files.eprints.org/3097/5/eprints-3.4.6.tar.gz
tar -xzvf eprints-3.4.6.tar.gz

Then put in the source code in place: 

mv eprints-3.4.6 /opt/eprints3
chmod 2775 /opt/eprints3
chown -R eprints:eprints /opt/eprints3

If you want a publications flavoured repository, then also: 

wget https://files.eprints.org/3097/6/eprints-3.4.6-flavours.tar.gz
tar -xzvf eprints-3.4.6-flavours.tar.gz
mv eprints-3.4.6/flavours/pub_lib /opt/eprints3/flavours
chmod -R g+w /opt/eprints3/flavours/pub_lib
chown -R eprints:eprints /opt/eprints3/flavours/pub_lib

Configuration

Next, as the eprints user copy EPRINTS_PATH/perl_lib/EPrints/SystemSettings.pm.tmpl to EPRINTS_PATH/perl_lib/EPrints/SystemSettings.pm, if it does not already exist.

EPRINTS_PATH should now always be /opt/eprints3. However, historically other paths have been used when EPrints was available as a Deb package.

EPrints is now fully installed at EPRINTS_PATH/. However, you will not yet have a running archive. Follow the Getting Started with EPrints 3 instructions to set this up.

Post-configuration

Next, add the file /etc/apache2/sites-available/eprints.conf with the following line: 

Include EPRINTS_PATH/cfg/apache.conf

To enable this as root run the command: 

root> a2ensite eprints

Also it may be necessary to disable the default site otherwise the default Apache page will still be shown: 

a2dissite 000-default

Finally, restart Apache: 

service apache2 restart

You should now be able to access your vanilla repository at the hostname you specified when running epadmin create from the Getting Started with EPrints 3 instructions. You should then login as the admin user you created during this process and turn on the indexer. This can be done by clicking on the Admin link under the Logged in menu, then clicking on the System Tools tab and finally the Start Indexer button.

Operating System Version Specific Requirements

Ubuntu 22.04 LTS

N.B. It is assumed that you are installing the latest version of 3.4. Earlier versions may have issues not listed here.

NO CURRENT ISSUES

Previous issues

libsepol1 Deb package no longer exists 
This has been removed as a dependency on 29th May 2022, as it is not specifically required by EPrints.
MySQL root user cannot be used 
This is now explained under EPrints' Getting Started instructions. As it is typical for most modern Linux operating systems.

Ubuntu 24.04 LTS

N.B. It is assumed that you are installing the latest version of 3.4. Earlier versions may have issues not listed here.

libncurses5 no longer available

libncurses5 APT package dependency no longer exists in Ubuntu 24.04 LTS, install libncurses6 instead.

Previous Issues
