I'm trying to install flatpak to install firefox on my docker container, but when I run my Dockerfile, I´m getting this error:
error: app/org.mozilla.firefox/x86_64/stable needs a later flatpak version (0.11.1)
I have tried to solve it by installing the flatpak version that the error says, but when I do that, another error raises:
E: Version '0.11.1' for 'flatpak' was not found
This is the Dockerfile:
RUN set -ex;
apt-get install -y
How can I solve this error?
