Hello Jack,

readline is not something you can meaningfully acquire using synaptic
package manager. Instead, if you install software that use readline,
synaptic will automatically install it. Otherwise installing it has
no effect. If you are building software using readline, you need to
install 'libreadline-dev' instead.

If you do that, you need to make sure PARI Configure find your readline

Hello Jack,
The official Debian package includes readline, and as far as I can tell
from <> so
does the Ubuntu version.

If you are trying to build PARI yourself, then you should do
sudo apt-get build-dep pari
so make sure all packages needed to build pari are installed,
including libreadline-dev.

If not, maybe someting is strange with you apt configuration.
What is your /etc/apt/sources.list and /etc/apt/sources.list.d/*
files ?
