Hello, the bug seems to be in Smarty, you should report this to ubuntu packagers

[artlog]

@vgdko You might want to switch to ubuntu 22.04. ubuntu impish (21.10) was an interim release and is currently end of life since July 14, 2022.

source : https://wiki.ubuntu.com/Releases?_ga=2.133627726.173820398.1658294831-1596732122.1658294831

This problem still exists in 22.04 package. There is now a bug report for it : https://bugs.launchpad.net/ubuntu/+source/smarty3/+bug/1986916

Since this smarty3 package is broken in 22.04. It should be installed manually from source

[artlog]

here a hacky way to replace smarty3 broken package with source based one, this is a temporary hack until ubuntu version gets fixed. Warning it does not uninstall package smarty3 at all, just overwrite it.

bash script

#!/bin/bash

smarty_version=v3.1.46

rm -rf /usr/share/php/smarty3/ 

mkdir -p /usr/share/php/smarty3/ && \
    curl -Lqs https://github.com/smarty-php/smarty/archive/${smarty_version}.tar.gz | \
    tar xzf - -C /usr/share/php/smarty3/ --strip-components=2

We could also install Smarty in another location (for example /usr/local/smarty3) and change the configuration in conf/config.inc.local.php :

define("SMARTY", "/usr/local/smarty3/Smarty.class.php");

Oh this is an unfortunate bug seeing as it has been fixed upstream months ago. A less ugly fix is to use smarty3 from Debian unstable:

# wget http://ftp.us.debian.org/debian/pool/main/s/smarty3/smarty3_3.1.47-2_all.deb
# dpkg -i smarty3_3.1.47-2_all.deb

This is working for me in Ubuntu 22.04.2. I'm not sure if I want to do this long term, but it works for now...
