Problem with apt-get update.

[Wond2]

Hi all.

I have some trouble.
I downloaded last distr (2.0.1r), create sdcard, boot Pi.
After loading I try to make update:

apt-get -y update

and have this message:

Ign https://raw.githubusercontent.com 250gto InRelease
Ign https://raw.githubusercontent.com 250gto Release.gpg
Ign https://raw.githubusercontent.com 250gto Release
Err https://raw.githubusercontent.com 250gto/main armel Packages

E: Some index files failed to download. They have been ignored, or old ones used instead.

And can't update and upgrade of course.

I think it's error from githubusercontent, because I have same message when I try download any script from https://raw.githubusercontent.com

For example

wget https://raw.githubusercontent.com/script.sh

...connected.
ERROR: cannot verify raw.githubusercontent.com's certificate, iddued by '/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert High Assurance CA-3':
Issued certificate not yet valid.

If I try download with '--no-check-certificates' flag - all is ok and script was downloaded.

So what's really wrong? How I can update if it problems with GitHub? Thanks!

Double check your internal date/time.
certificates are checked twice and matched with your current datetime settings, that's because github uses https.
try to:

• set your date-time manually or
• ntpdate pool.ntp.org and then issue the date command to see if you've a correct date. No matter about the timezone but the date must not be 1970-01-01

When you're set try with the common apt-get update or use wget or whatever tool you'd like

Thanks, it's helped. But when I change my internet-source (from eth0 lan to another eht0 lan) it's not work and time was change back. But it's ok. Thanks again.
