Error Installing Oct 2020 release

When trying to update OSMC from 2020.06 to 2020.10 I’m getting an error on screen that just says “Error Installing” and advises to post on the OSMC forum.

It’s a Raspberry Pi 3B.

I’ve enabled Debug Logging, rebooted twice, ran the update again (same error).
Tried to use grab-logs -A but that just hung for 10+ minutes and never actually seemed to do anything.

I’ve taken the kodi.log and uploaded it manually to here:
http://paste.osmc.io/yamupaseqo.vhdl

I’m assuming this is the problem area, but I don’t know what the fix is for this?

DEBUG: script.module.osmcsetting.updates : - apt_updater encountered and error:
Exception : Error Type and Args: FetchFailedException : (Error(“E:The repository ‘http://apt.osmc.tv stretch Release’ does no longer have a Release file., W:Updating from such a repository can’t be done securely, and is therefore disabled by default., W:See apt-secure(8) manpage for repository creation and user configuration details., E:The repository ‘Index of /debian stretch Release’ does no longer have a Release file., W:Updating from such a repository can’t be done securely, and is therefore disabled by default., W:See apt-secure(8) manpage for repository creation and user configuration details., E:The repository ‘Index of /debian stretch-updates Release’ does no longer have a Release file., W:Updating from such a repository can’t be done securely, and is therefore disabled by default., W:See apt-secure(8) manpage for repository creation and user configuration details., E:The repository ‘http://security.debian.org stretch/updates Release’ does no longer have a Release file.”,),)

Try grab-logs -a that should be smaller and still give some ideas.
Or reboot twice and then try grab-logs -A

Thanks!

I may have solved it though…
I changed DNS server to 8.8.8.8 and it’s now downloaded the package and doing the update.

Interesting what was it before? your local DNS server?

Yeh, just my local router. My local router is set to use Cisco DNS servers, as they are faster than Google.

Yep, working fine now - so consider this resolved please.
