Looks like it’s now called _testing-security_
[http://security-cdn.debian.org/debian-security/dists/](http://security-cdn.debian.org/debian-security/dists/)
Replace testing with testing-security in all the security lines in /etc/apt/sources.list
You can also remove the lines. See [FAQ](https://www.debian.org/security/faq#unstable)

Thank you again, Joseph! I corrected the lines in the sources.list. Now programs are installed! And what needs to be corrected that my Freedombox updated? (Post here: [Freedombox is not updated](https://discuss.freedombox.org/t/freedombox-is-not-updated/669))

The same correction might work for system updates too.
After making the above changes, did you try doing a manual update from the Update app under System?

Applications are not installed again after the system upgrade. For example, when I try to install Storage, I get a message:
Error during installationE: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable) E: Unable to lock directory /var/lib/apt/lists/

Written for Ubuntu users, but likely helpful here:
[[Solved] Could not get lock /var/lib/dpkg/lock Error in Ubuntu](https://itsfoss.com/could-not-get-lock-error/)
From the link:
> You see this error because some other program is trying to update […]. When a command or application is updating the system or installing a new software, it locks the [Debian package manager] file […].
Write down what you try and if it doesn’t work, post back here.

@dgj Thank you for help! Yes, I receive a message on the Storage page that another installation or upgrade is in progress. But I 've been seeing this message for two days. If I reload the Install Storage page, it disappears. I start the installation and get a message again: Error during installationE: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable) E: Unable to lock directory /var/lib/apt/lists/
I get similar messages when I try to install other programs.
Thanks for the link, I 'll study all the methods.
