Debian bullseye repo missing Release file

[jdpiguet]

I want to test dattobd.
I have done a fresh install of Debian 11.2.
Tried to install dattobd following instructions from INSTALL.md.

First the prerequisites:

root@vboxtesting:~# apt install -y linux-headers-$(uname -r) build-essential
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
build-essential is already the newest version (12.9).
linux-headers-5.10.0-10-amd64 is already the newest version (5.10.84-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

root@vboxtesting:~# apt-key adv --fetch-keys https://cpkg.datto.com/DATTO-PKGS-GPG-KEY
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

deb [arch=amd64] https://cpkg.datto.com/datto-deb/public/bullseye bullseye main

Second update the repositories cache:

root@vboxtesting:~# apt update

Hit:2 http://mirror1.infomaniak.com/debian bullseye-updates InRelease

root@vboxtesting:~# 

"apt update" fails due to missing Release file?

Hi jdpiguet,

Even if you install the current dattobd package, it doesn't work.
Because the Debian 11.2 kernel is 5.10.
Not able to support this kernel version.

If you want to test, you should try elastio-snap.

Please find below a link.

And you can build the package by installing debbuild.
For Debian, please install the following.
https://github.com/debbuild/debbuild/releases
https://secure.deepnet.cx/trac/debbuild

• debbuild_21.01.0-0ubuntu20.04_all.deb
• perl
• build-essential
• pax (used for .sdeb source packages)
• fakeroot

Any update on this? Here it is May 2022 and there is still no support for Debian 11. What is taking so long to get this working? Its been almost a year since Debian 11 has been released
