libappindicator3-1 package does not exist in Debian testing (and probably won’t in the upcoming stable release). The package is subject to be [removed](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=895037) [from](https://lists.debian.org/debian-devel/2018/03/msg00506.html) [Debian](https://wiki.debian.org/Ayatana/IndicatorsTransition). Proposed solution by Debian: migrate to libayatana-appindicator. **Delta Chat version** deltachat-desktop\_1.14.1\_amd64.deb **Expected behavior** debian package to be installed after ```auto dpkg -i deltachat-desktop_1.14.1_amd64.deb apt install -f ``` **Actual behavior** ```auto Selecting previously unselected package deltachat-desktop. (Reading database ... 337287 files and directories currently installed.) Preparing to unpack deltachat-desktop_1.14.1_amd64.deb ...
