[SRU] Backport Go 1.20 to Jammy

[Denison Barbosa]

[Impact]

* We have customers who want the new version of adsys backported to Jammy and it requires the 1.20 version of the Go toolchain. This can be achieved by backporting the golang-1.20 package, which is available in Lunar, to Jammy as a separate versioned package.

[Test Plan]

1. Ensure Golang 1.20 is published in -proposed;
2. Start a build with a package that requires Golang 1.20 (dependency + PATH set to the Golang 1.20 go binary)
3. Ensure the package builds successfully;
4. Run "go version" which should display: "go1.20.x" (x being the version uploaded).

[Where problems could occur]

* Packages that depend on the new version not being able to compile;
* Since it's a separate package rather than an update of the current one, there will be no difference on the existing ecosystem.

This debdiff should be enough for the backporting of the golang-1.20 package.

[Ubuntu Foundations Team Bug Bot (crichton)]

The attachment "jammy1.diff" seems to be a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. If the attachment isn't a patch, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are member of the ~ubuntu-sponsors, unsubscribe the team.

I just review the debdiff.
1. no need to downgrade debhelper-compat, jammy has debhelper 13, so it just works.
2. please use version 1.20.3-1~22.04, so it's consistent with other golang-1.x SRU.

@justdenis thanks for the update. LGTM

@didrocks could you continue uploading it to the archive? (I'm still not a core dev with uploading rights).

[Shengjing Zhu (zhsj)]

@justdenis oh i think you miss the LP bug number in the changelog.

[Denison Barbosa (justdenis)]

Oops, thanks for the heads up @zhsj! Here's the fixed one.

An upload of golang-1.20 to jammy-proposed has been rejected from the upload queue for the following reason: "misses security fixes from 1.20.3-1ubuntu0.1 / 1.20.4 upstream".

[Benjamin Drung (bdrung)]

Since the debdiff is trivial, I rebased the debdiff on 1.20.3-1ubuntu0.1 and uploaded 1.20.3-1ubuntu0.1~22.04 to jammy.

Hello Denison, or anyone else affected,

Accepted golang-1.20 into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/golang-1.20/1.20.3-1ubuntu0.1~22.04 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.

I installed the golang-1.20 1.20.3-1ubuntu0.1~22.04 from jammy-proposed.

+ I execute the `/usr/lib/go-1.20/bin/go version` command, and the output is `go version go1.20.3 linux/amd64`.
+ I rebuild several Go packages (adsys/0.8.4, containerd/1.5.9-0ubuntu3) with golang-1.20. They all build successfully.

This bug was fixed in the package golang-1.20 - 1.20.3-1ubuntu0.1~22.04

The verification of the Stable Release Update for golang-1.20 has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
