Package: gdebi-core Version: 0.9.5.7+nmu3 I just installed Debian 10.0.0 and gdebi-core. When I run gdebi, I get warning similar to the one described and fixed in bug 911868:
# gdebi <package>_all.deb Do you want to install the software package? [y/N]:y /usr/bin/gdebi:113: FutureWarning: Possible nested set at position 1 c = findall("[[(](\S+)/\S+[])]", msg)[0].lower() -- Juha
