If you are running a GNU/Linux system, you could try the new Tramp file
archive feature. Try with a recent Emacs from master

M-x load-library tramp
M-x url-handler-mode
C-x C-f 
http://free.nchc.org.tw/debian/pool/main/g/getmail4/getmail4_4.53.0-1+deb9u1_all.deb/

Note the trailing slash. You could even open

C-x C-f 
http://free.nchc.org.tw/debian/pool/main/g/getmail4/getmail4_4.53.0-1+deb9u1_all.deb/control.tar.xz/control

Best regards, Michael.
