Installing SIP client Blink on Debian 11

Blink is my favourite SIP client. I’ve used in on macOS for years, and I’m pleased it is also available for Debian.

Installation instructions for Debian are here.

Importing the key

Installing the signing key is fine.

Update 2023-04-08: it was not fine when I went to reinstall blink.

I got an error message saying:

W: GPG error: bullseye InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F74046C316D8F9F5

I tried importing the key with:

gpg --keyserver hkp:// --recv F74046C316D8F9F5

This did process and import the key, but the error message persisted.

I ended up forcing apt to trust the repository, but adding [trusted=yes] after deb/deb-src in the repository list.

Adding the repository

In terms of adding the repository, I did two things differently.

First, the instructions say:

Depending on your Linux OS version add the following lines to /etc/apt/sources.list:

My preference - and it is only a preference - is not to have one massive sources.list file. So I prefer to add the repository information to a custom file, in /etc/apt/sources.list.d/. For example, blink.list: /etc/apt/sources.list.d/blink.list. I just find it easier to manage/maintain.

In terms of the repositories, the official instructions still show Debian 10 / Buster as being “stable”:

deb buster main 
deb-src buster main

Fortunately, one can replace buster with the actual current stable version, bullseye, and it works fine:

deb bullseye main 
deb-src bullseye main

Once you’ve added the repositories, it’s the normal routine of:

sudo apt update

to ingest information from the new repository, then

sudo apt install blink -y

to install blink.

It pulls in a lot of dependencies:
