Both packages have the same name, so the package manager treats them as the same. Rename the package name of the old version (e.g. to master- pdf-editor-4) and you should be fine. There are probably better ways, but just listing one of them, assuming the old file is named master-pdf-editor-4.deb for this you could do: ar x master-pdf-editor-4.deb control.tar.gz gzip -d control.tar.gz tar xf control.tar ./control sed -i '1,1 { /^Package:/{ s/$/-4/} }' control gzip control.tar ar r master-pdf-editor-5.7.53-qt5.x86_64.deb control.tar.gz (this works on their v5 .deb, watch out if on your .deb, names are slightly different, such as using xz rather than gz) > >
