Ubuntu – How to make APT ignore the validity of the Release file

aptUbuntu

I'm getting these errors whenever I try to run apt update:

E: Release file for http://de.archive.ubuntu.com/ubuntu/dists/bionic-updates/InRelease is not valid yet (invalid for another 244d 19h 25min 34s). Updates for this repository will not be applied.

I've seen answers mentioning -o Acquire::Check-Valid-Until=false, but that doesn't work as it seems to be only for system dates in the future or expired repos.

Yes, I know that the system date is wrong. Back in the past in fact.

How do I make apt use those Release files, ignoring the validity of them or the system date?

Try -o Acquire::Max-FutureTime=31536000

31536000 is one year in seconds, which should be enough to accommodate your clock being so far behind.

If you wish to search a specific string only in package names, you can do:

apt-cache search --names-only 'xxx'

This will return anything that contains 'xxx' in their package name.

You can also use regular expressions:

apt-cache search --names-only 'php5$'

This will return any package with their name ending in php5.

Regular expressions can also be used without the --names-only. See apt-cache(8) man page.
