Install Apertium core using packaging

You are using a Debian/Red Hat-based operating system. You want a fast clean install.

You could use a public repository but you will be more up-to-date with the Apertium package repository.

The Apertium package repository

Tino Didriksen provides a repository of Debian/RPM packages. Downloading packages from there, you can install all prerequisites and Apertium tools. You also get, for optional install; release-level language pairs, service providers, constraint grammar code, and more. All under package management.

Before we start, a comment from the mail list, from an admin-level contributor,

If you're going to be developing, I'd say pick nightly. The -release versions of lttoolbox and apertium might not be up-to-date with what apertium-init expects.

Debian-based

If you have a Debian or Debian-based system (e.g. Ubuntu, Mint...).

First, remove any Apertium packages you have installed from operating system repositories. They will be out-of-date, sometimes by years.

Add the repository,

# Pick one:

# Nightly, unstable, new, almost always use this:
curl -sS https://apertium.projectjj.com/apt/install-nightly.sh | sudo bash

# Release, stable, old:
curl -sS https://apertium.projectjj.com/apt/install-release.sh | sudo bash

You should see messages.

Install dev tools,

sudo apt-get -f install apertium-all-dev

Note: If you get any errors such as uninstallable unmet dependencies, try updating your ubuntu to the latest normal version.

About the Debian repository install

Check the script installed Apertium repository details,

apt-cache policy | grep apertium

Unfortunately, due to the seamless upgrading of Debian packaging, it is difficult to see which packages the new repository has added, and where. Even Synaptic, the wonder GUI, has no way through. You could try this brute force commandline,

find /var/lib/apt/lists/ |grep projectjj.*Packages | xargs grep -h Package

Which will, if nothing else, tell you a lot about byways of the Apertium project.

Cleaning up a mixed install

If you have installed some of the core tools from source and want to switch to packages, you can remove the source install with something like this. Be extremely careful with getting this right so it doesn't wipe your whole machine. (If Apertium isn't working no matter what you try, then this is a helpful step to take after uninstalling and reinstalling it)

# Wipe most files
rm -rfv /usr/local/*/*apertium* /usr/local/*/*/*apertium*
rm -rfv /usr/local/bin/lt-* /usr/local/bin/lrx-* /usr/local/bin/lsx-*
rm -rfv /usr/local/*/*lttoolbox* /usr/local/*/*/*lttoolbox*
rm -rfv /usr/local/*/*hfst* /usr/local/*/*/*hfst*
rm -rfv /usr/local/bin/cg-*
rm -rfv /usr/local/*/*cg3* /usr/local/*/*/*cg3*

# Wipe any certain conflicting file
grep -h '^Package:' /var/lib/apt/lists/apertium.projectjj.com* \
| awk '{print $2}' | xargs -rn1 dpkg-query -L 2>/dev/null | grep '^/usr' \
| xargs -rn1 '-I{}' bash -c "if [[ -f '{}' ]]; then echo '{}'; fi;" \
| sed 's/\/usr\//\/usr\/local\//;' | xargs rm -fv

Red Hat-based

If you have a RHEL/CentOS/Fedora/OpenSUSE or similar system.

First, remove any Apertium packages you have installed from operating system repositories. They will be out-of-date, sometimes by years.

Add the repository,

# Pick one

# Nightly, unstable, new, almost always use this:
curl -sS https://apertium.projectjj.com/rpm/install-nightly.sh | sudo bash

# Release, stable, old:
curl -sS https://apertium.projectjj.com/rpm/install-release.sh | sudo bash

Install dev tools,

# RHEL/CentOS:
sudo yum install apertium-all-devel
# Fedora:
sudo dnf install apertium-all-devel
# OpenSUSE:
sudo zypper install apertium-all-devel

Arch Linux

curl -sS https://apertium.projectjj.com/archlinux-apertium-all-dev.sh | sudo bash

And now...

Maybe you want to test this is working. So download a test language, Install language data using packaging. Then Install quick tests can make you sure.

If you know you need the HFST or CG3 modules, packages are available, or see Installation of grammar libraries. You may also be interested in the many tips at Bash completion.

If you are developing, now you can Install language data by compiling or How to bootstrap a new pair. If you are not, Install language data using packaging and go speak many languages :)
