Seeding new ISOs the easy zsync way

Kubuntu recently had to pull our 17.10 ISOs because of the so-called lenovo bug. Now that this bug is fixed, the ISOs have been respun, and so now it's time to begin to reseed the torrents.

To speed up the process, I wanted to zsync to the original ISOs before getting the new torrent files. Simon kindly told me the easy way to do this - cd to the directory where the ISOs live, which in my case is 

cd /media/valorie/Data/ISOs/


cp kubuntu-17.10{,.1}-desktop-amd64.iso && zsync

Where did I get the link to zsync? At All ISOs are found at cdimage, just as all torrents are found at

The final step is to download those torrent files (pro-tip: use control F) and tell Ktorrent to seed them all! I seed all the supported Ubuntu releases. The more people do this, the faster torrents are for everyone. If you have the bandwidth, go for it!

PS: you don't have to copy all the cdimage URLs. Just up-arrow and then back-arrow through your previous command once the sync has finished, edit it, hit return and you are back in business.
