Tilix is actually available in the Deepin repositories:
packages.deepin.com/deepin/pool/main/t/tilix (you could just download the .deb from there and install with
dpkg
, but this really shouldn't be necessary). First, try running
sudo apt update
and then
sudo apt install tilix
. Does that work? If not, please
edit your question and show us the contents of your
/etc/apt/sources.list
and any files in the
/etc/apt/sources.list.d
directory. Also show us the output of
apt-cache search tilix
after running
apt update
. —
