Hello Julian, or anyone else affected,

Accepted apt into jammy-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/apt/2.4.11 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  [Impact]
  The snapshot service provides users access to older states of the archive 
with ease of use, and enables a consistent user experience across all supported 
releases, as otherwise users would have to rewrite their sources.list to make 
use of snapshots and set up pinning; hence partners requested the feature be 
SRUed to older releases as well.

  [Test plan]
  The complete regression test suite in autopkgtests includes an automatic test 
case for this and the known limitations that have been fixed. Aside from that, 
it is also worthwhile to do an end-to-end test:

  Configure snapshot=yes for Ubuntu sources in your sources.list and

  1. run apt update - it should not use snapshot
  2. run apt update --snapshot 20231001T000000Z, it should download the snapshot
  3. run apt policy --snapshot 20231001T000000Z hello, it should show hello in 
the snapshot
  4. run apt install --snapshot 20231001T000000Z hello, it should install hello 
from the snapshot
  5. Run apt update; observe snapshot not being downloaded
  6. Observe snapshots are gone from /var/lib/apt/lists again

  [Where problems could occur]
  The integration has been purposefully limited in how it works to reduce the 
impact it has on the APT code; hence it was possible to cherry-pick this into 
22.04, 20.04, and even 18.04, with only a minor editorial change. This 
significantly limits the risk.

  This feature is only enabled for sources with snapshot=yes (.list) or
  Snapshot: yes (.sources) or other truthy values apt recognizes. Most
  users will not have such entries as they did not have an APT
  supporting it.

  This combined should ensure that users do not experience any
  regressions. However the feature may be lacking in some ways that we
  may want to address in follow up SRUs; it has not been used in the
  wild a lot.
