Hi @ckruijntjens and @MarcusRieche,
I have just pushed an update of the packages that now include 5.25.5, which is the current “Extended Support Release” of Mattermost. Please be aware that this will very likely be the last update to these packages.
To continue using Mattermost please follow the official installation instructions to choose an alternative install method. Migration instructions can be found in the Mattermost documentation.
