Add Percona's Debian repository and XtraBackup. Remove
libcurl4-gnutls-dev as it conflicts with the libcurl4-openssl-dev
requirement (I think that it would work just as well).

I need it for some project and it seems to me to belong here instead of
rcfiles.

Already using pgcli and mycli, now adding iredis and litecli (for Redis
and SQLite).

I broke down. I need multiple versions of Python and a bunch of
different things on occasion.

This adds flatpak-spawn as well.

Use the replacement XDG utilities for Flatpak containers to replace
standard xdg-open and xdg-email so they work as expected inside the
container.

The GitHub CLI requires authentication (even though listing releases
doesn't require authentication). Fallback to to using cURL.

It's been deprecated and removed. The alternative is go install but it's
not a direct replacement. Specifically, replace directives can't appear
in the go.mod file. Kustomize can be installed using go install, so
that's fine. RKE and reg can't, so use the GitHub CLI to download the
binaries from the latest release.

It's not building anymore. Keybase seems unmaintained (since they were
bought by Slack). I don't use it anymore.

And the repo key URL.

Silence a warning.

The limitation was added in 3c6e6607 because Debian at the time didn't
had the required minimum version of the Connector/C. Now it has.

For programmatically managing Transmissions using Python. Exciting.

There's no repository so I download the package from the GitHub release.
It maybe a little better from the worked around build process, less
code, less fragile and probably a little faster to build.

I wasn't too happy with having another package manager (APT and the
language specific managers seemed enough) and there security issues when
running as a regular user. Before running it for the first time as root
worked and I didn't it need afterwards. Now however, it refuses to even
run once.

Build the go binary from source. It's more complex than just go get or
go install, see https://github.com/kubernetes/kompose/issues/1472 from
more information. This the last Homebrew package. Now to remove
Homebrew.

Buid the go binary. Leaving just one last package from Homebrew. It's
days are numbered!

go get is being deprecated in favor of go install and modules. Run go
get commands before setting GO111MODULE.

Build the Go binary. And another Homebrew package is removed.

Requires their package from kubectl. Another Homebrew item removed.

Build the Go binary. One less thing using Homebrew.

The fix is installing the ca-certificates package before adding the
source files. Doing that would make the 2 build stages close enough that
it doesn't make sense anymore to have 2 build stages.

Try to disable GitLab runner's umask fiddling and see if that works (it
might, you don't know).

- Don't use the builddeps image since it no longer tracks Debian
  testing. Use the same image in all stages of the build (save some
space).
- Install gnupg and curl in the stage that fetches the repos keys.
- Merge the APT installs in the final build stage. There's no need to
  install anything before running apt-get update (once the files are in
place).
- A little nicer handling of GPG keyrings (stole from the Datadog agent
  installation instructions).
