Sky (skype for business) broken

I’m trying to install it, but the download fails:

curl: (22) The requested URL returned error: 404 Not Found
error: cannot download sky_2.1.7369-1ubuntu+xenial_amd64.deb from any mirror

I think, the URL must be changed to:

https://tel.red/repos/ubuntu/pool/non-free/sky_2.1.7772-1ubuntu%2Bxenial_amd64.deb

as sky_2.1.7369 seems to be removed from the downloads.

And: are there any plans to move to the 20.04 focal deb?

I couldn’t reach the maintainer of the package via email, that’s why I ask the question here in the forums.

I guess there are no such plans:

https://github.com/NixOS/nixpkgs/pull/98125

Feel free to @ me, if you want to reintroduce this with yourself as maintainer.

Hey since I was the maintainer you can send me a mail via github@otlingha.us

I wasn’t aware of:

SKY LINUX IS FREE AS IN BEER, WITH 2 MINUTE LIMIT ON CALLS & SCREEN SHARE

I’m currently not using it on a professional basis, I won’t spend 50$/year on it for now.
I’m sorry, this means I’m out as a maintainer for that software.
