Hi,

a while back I wrote a script to download the Ubuntu flavours that were
available that time and to automatically check the downloaded ISO
against the signed checksum. It still works.

Save the script, then make it executable by

cd /location/where/the/script/is/stored
chown username:username luamd64_1610.sh

(usually running  chown 1000:1000 luamd64_1610.sh  should do the job,
too)

after that you could run the script, e.g.

./luamd64_1610.sh ubuntustudio 18.10

to get a verified ubuntustudio 18.10.

Regards,
Ralf
