Problem with Jeanie installer Ubuntu

[agenda51]

I had an issue installing DF with jeanie.
It was due to an outdated installation version of couchbase.
To correct it I modified the necessary part by this :

INSTALL COUCHBASE

php -m | grep -E "^couchbase"
if (($? >= 1)); then
if ((CURRENT_OS == 16)); then
wget -P /tmp http://packages.couchbase.com/releases/couchbase-release/couchbase-release-1.0-4-amd64.deb
dpkg -i /tmp/couchbase-release-1.0-4-amd64.deb

elif ((CURRENT_OS == 18)); then
wget -O - https://packages.couchbase.com/clients/c/repos/deb/couchbase.key | apt-key add couchbase.key -
echo "deb https://packages.couchbase.com/clients/c/repos/deb/ubuntu1804 bionic bionic/main" >/etc/apt/sources.list.d/couchbase.list
fi

apt-get update
apt install -y libcouchbase3 libcouchbase-dev libcouchbase3-tools libcouchbase-dbg libcouchbase3-libev libcouchbase3-libevent
pecl install couchbase
if (($? >= 1)); then
echo_with_color red "\ncouchbase extension installation error." >&5
exit 1
fi
echo "extension=couchbase.so" >"/etc/php/${PHP_VERSION_INDEX}/mods-available/xcouchbase.ini"
phpenmod -s ALL xcouchbase
php -m | grep couchbase
if (($? >= 1)); then
echo_with_color red "\nCould not install couchbase extension." >&5
fi

fi
