I want to use zsync to download the beta (and the August 18.3 iso).
I see the zsync "files" listed on sourceforge.net but because of their mirrors or something the .zsync url doesn't link to the actual file.
Is there an easy way to do that?
Yea, zsync-ing from sourcefourge is a bit tricky.
The attached zsync-helper script will get first closest mirror before the actually zsync is taking place:
The best result you would have with "binary" close iso.
Ok just testing how it would go, using MX18.3 iso (which is not very "binary" close):
Code: Select all
./zsync-mx-19-testing.sh MX-19beta-1_x64.iso MX-18.3_August_x64.iso
Well at least it tells us that "Target 22.5% complete."
Code: Select all
./zsync-mx-19-testing.sh MX-19beta-1_x64.iso MX-18.3_August_x64.iso
Downloading "MX-19beta-1_x64.iso" file
MX-19beta-1_x64.iso
Using input file: MX-18.3_August_x64.iso

) . Why ? I remember, times ago, someone altered iso files of Manjaro or Mint on their original repositories(website) and that was noticed by admins, hours later!
