Hi [NAME],   It seems that source list link that you have enter is incorrect.   Could you check on the product-version is not 620, it should be 950, since you are installing OMSA 9.5.    $ sudo echo 'deb [URL]{product-version}/{release-name} {release-name} main' | sudo tee -a /etc/apt/sources.list.d/linux.dell.com.sources.list
Hi, I tried to install Dell OMSA v9.5.0 on our PowerEdge R620 running Ubuntu 20.04.3 LTS, but encountered the below error upon running "apt-get update": Hit:1 [URL] focal InReleaseHit:2 [URL] stable InReleaseHit:3 [URL] focal InReleaseHit:4 [URL] focal InReleaseHit:5 [URL] focal-updates InReleaseHit:6 [URL] focal-backports InReleaseHit:7 [URL] focal-security InReleaseIgn:8 [URL] focal InReleaseErr:9 [URL] focal Release404 Not Found [IP: 143.166.156.113 443]Reading package lists...

Followed steps from: [URL]   linux.dell.com.sources.list file: deb [URL] focal main   Is there any other repos I can use to install OMSA on R620 for Ubuntu 20.04.3 LTS Focal? Thank you.
