[Bug 1977860] Re: Backport 1.18.3 to 20.04 and 22.04 LTS

[Christian Ehrhardt ]

Thanks for bringing this up, that will indeed not work out as-is.
Discussed with the SRU team (as this is their territory) and agreed that it should be removed (as also acknowledged by Didier in comment #9) from focal-proposed for a new upload to be provided by Lucas (thanks for volunteering).

Also good on a second check, all golang 1.18 are only in focal-proposed nothing reached focal-updates yet.
 golang-1.18-src | 1.18.3-1ubuntu1~20.04 | focal-proposed/universe | all
 golang-1.18-go | 1.18.3-1ubuntu1~20.04 | focal-proposed/universe | amd64, arm64, armhf, ppc64el, riscv64, s390x
 golang-1.18-doc | 1.18.3-1ubuntu1~20.04 | focal-proposed/universe | all
 golang-1.18 | 1.18.3-1ubuntu1~20.04 | focal-proposed/universe | source, all


Therefore it was now removed.

@Lucas - assigning you now to prep a valid backport of the one in jammy

Title:
  Backport 1.18.3 to 20.04 and 22.04 LTS

Status in golang-1.18 package in Ubuntu:
  Fix Released
Status in golang-1.18 source package in Focal:
  Fix Committed
Status in golang-1.18 source package in Jammy:
  Incomplete

Bug description:
  [Rationale for update in 22.04]
  As requested by sil2100, we don’t want upgrade from 20.04 LTS downgrading the Golang 1.18 version. Hence updating this package too to 1.18.3 which includes multile security fixes compared to 1.18.1:

  - go1.18.2 (released 2022-05-10) includes security fixes to the
  syscall package, as well as bug fixes to the compiler, runtime, the go
  command, and the crypto/x509, go/types, net/http/httptest, reflect,
  and sync/atomic packages. See the Go 1.18.2 milestone on our issue
  tracker for details.

  -  go1.18.3 (released 2022-06-01) includes security fixes to the
  crypto/rand, crypto/tls, os/exec, and path/filepath packages, as well
  as bug fixes to the compiler, and the crypto/tls and
  text/template/parse packages. See the Go 1.18.3 milestone on our issue
  tracker for details.

  
  [Rationale for new package in 20.04]

  As part of our entreprise desktop offering, we need to backport a recent version of ADSys to 20.04 LTS.
  This version depends on a recent Go version for embedding and more (golang 1.18), thus we need to backport Go 1.18 as a new separate binary package, as it’s already the case for current adsys and the backport of 1.16.

  [Test Plan]

   1. Ensure Golang 1.16 is published in -proposed
   2. Start a build with a package, requiring Golang 1.18 (dependency + PATH set to Golang 1.18 go binary).
   3. Ensure the package builds successfully.
   4. Run go version <your binary> which should display: "go1.18.x" (x being the version uploaded).

  [Where problems could occur]
   * Package depending on this Go version would not be able to compile.
   * As this is a separate, versionned, new package, no impact on existing ones.
   * FYI, we already built ADSys against this Go version in our ppa: https://launchpad.net/~didrocks/+archive/ubuntu/ppa
