Package: debian-edu-config Version: 2.10.65+deb10u4 Severity: important Since some time, new users are faced with an 'insecure certificate' and have to accept it if they want to use mail inside the internal Debian Edu network. Reason for this has been a change in the way Thunderbird sets up profiles (randomly named subdir). Now that Thunderbird support for system-wide policies has been enabled, it is easy to fix it: A policy file /usr/lib/thunderbird/distribution/policies.json will make sure that the Debian-Edu_rootCA.crt file gets installed as trusted certificate for Thunderbird. File content: { "policies": { "Certificates": { "ImportEnterpriseRoots": true, "Install": [ "/etc/ssl/certs/Debian-Edu_rootCA.crt" ] } } } Wolfgang
