Thank you for your help! Please let me elaborate a bit. I need php >=7.1 for installing Kimai, not for SugarCRM. I just can’t get it done in ways alike described here. These are the errors:
$ sudo apt-get update
E: The repository ‘https://packages.sury.org/php Blumenthal Release’ does not have a Release file.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
$ sudo apt-get install -y php7.3 php7.3-cli php7.3-common

E: Unable to locate package php7.3-common
E: Couldn’t find any package by glob ‘php7.3-common’

What am I doing wrong? Is there any other way or should I better not install Kimai in an Univention environment?
