[Slackbuilds-users] bad downloads, courtesy of sbosrcarch

[B Watson]

Failed md5sums:

gis/rasterio
network/vivaldi (32-bit download only, x86_64 is OK)
office/texlive

404 Not Found:

network/signal-desktop
network/youtube-dl (file exists under "releases" but not "latest")

The entire website for signal-desktop's download
(https://updates.signal.org/) is messed up, and I can't find the file
elsewhere. Actually... why is signal-desktop using a .deb? There's
source here:

https://github.com/signalapp/Signal-Desktop/releases

Is it one of those that's a bear to build, like palemoon or qt5?
