Hello, i have a problem of sources with SOGo, just now, before no problem of updates.
The website is working, and the repository is correct so i don't understand what's wrong..

My source is like that :

deb https://packages.inverse.ca/SOGo/nightl … ian/dists/ stretch stretch

But the error when apt-get update is :
Ign:12 https://packages.inverse.ca/SOGo/nightly/4/debian/dists stretch/stretch Translation-en
Ign:9 https://packages.inverse.ca/SOGo/nightly/4/debian/dists stretch/stretch all Packages
Err:10 https://packages.inverse.ca/SOGo/nightly/4/debian/dists stretch/stretch amd64 Packages
