There have been several Tumbleweed snapshots over the last few days. But today we saw the first with a 2018 snapshot date. So I decided to do a test install.
As usual, I used “aria2c” to download the iso (“openSUSE-Tumbleweed-DVD-x86_64-Snapshot20180101-Media.iso”). I also downloaded the sha256 checksum file. I then verified the gpg signature on the checksum file. Then I verified the checksum on the iso, to make sure that I had a good download.
