apt-get - select the oldest google-chrome file in sources.list.d

  • 772

In the folder /etc/apt/sources.list.d I have the file:

google-chrome-repo.list:

deb [arch=amd64 signed-by=/usr/share/keyrings/google-chrome-keyring.gpg] https://dl.google.com/linux/chrome/deb/ stable main
deb-src [arch=amd64 signed-by=/usr/share/keyrings/google-chrome-keyring.gpg] https://dl.google.com/linux/chrome/deb/ stable main

and in the folder /usr/share/keyrings i have a file named google-chrome-keyring.gpg

If I install google-chrome:

sudo apt-get install google-chrome-stable

That annoying second file is created in /etc/apt/sources.list.d with the name google-chrome.list, with content:

### THIS FILE IS AUTOMATICALLY CONFIGURED ###
# You may comment out this entry, but any other modifications may be lost.
deb [arch=amd64] https://dl.google.com/linux/chrome/deb/ stable main

and the file in the /etc/apt/trusted.gpg.d folder named google-chrome.gpg

If I don't delete the annoying autogenerated file /etc/apt/sources.list.d/google-chrome.list, then the command:

sudo apt-get purge google-chrome-stable

will give the following error:

E: Conflicting values set for option Signed-By regarding source https://dl.google.com/linux/chrome/deb/ stable: /usr/share/keyrings/google-chrome-keyring.gpg != 
E: The list of sources could not be read.

My goal instead is to be able to do apt-get install and apt-get purge of google-chrome as many times as I want, without first having to delete the autogenerated file each time.

How can i get this? Is there a way to make apt-get ignore that file?

The solutions proposed in other topics like delete that file are not really functional.

I want to be able to use apt-get directly as written above and not scripts or substitute functions.

It would be nice if there were some Dpkg::Options::= like:

Of multiple coincident files in "sources.list.d", only consider the oldest one (the one created first).

    I don't think what you explicitly asks is possible (to use only the oldest source file).

    But instead, you can make a DPkg::Post-Invoke command that runs after using apt/dpkg to remove the file you don't want.

    Create the file /etc/apt/apt.conf.d/100post-invoke (you can call it anything you like) with the contents:

    # This is a list of shell commands to run after invoking dpkg/apt-get #
DPkg::Post-Invoke { "rm -f /etc/apt/sources.list.d/google-chrome.list"; };

    Now, after running any apt install or apt purge command, the file /etc/apt/sources.list.d/google-chrome.list will be deleted (or ignored if it doesn't exist).

    You can of course add any number of commands to the /etc/apt/apt.conf.d/100post-invoke file to customize the behavior of apt/dpkg.
