[18.04] apt update failed

[quanxian]

Description:

After installing 18.04 beta1, apt update will fail.

1: InRelease is invalid
Solution: After changing system time 10 hours later, passed. Seems old image point to new release. But don't come across this issue before.
2. After In Release bug, when update package*.gz, there are some mismatches happens.

Seems the packages information is not consistent with detailed packages list.
Repo info from http://cn.archive.ubuntu.com/ubuntu/ubuntu/dists/bionic/.
Note: gz is almost one day earlier than the InRelease time. Content of gz is consistent with content of InRelease?

This block our testing.

Any solution for that?

But still need to update system date to be several hours late. :)

This sort of inconsistency shouldn't happen on mirrors which use the recommended 2-stage sync: https://wiki.ubuntu.com/Mirrors/Scripts Currently cn.archive.ubuntu.com is redirected to us.archive.ubuntu.com, so if the latter works for you, the former should also. I've just confirmed that I can deploy bionic cloud images and run apt updates on them, so my guess is that you're dealing with a local DNS override or troublesome transparent proxy.
