Head over to the project’s Copr page to get more in detail information. In short, you can run the following commands to enable the repository and install the Back in Time Qt4 based UI:
dnf copr enable mhoeher/backintime dnf install backintime-qt4
If you find any issues with the packages installed from the fedora-backintime repository, please feel free to report this in our bug tracker. Keep in mind that we are - in this case - just packaging existing software for Fedora. In case of bugs in the software itself (vs. bugs in the packaged software), we might have to report this against the upstream projects.
Building the RPMs on your own
If you are interested in building the RPM packages on your own, feel free to head over to our GitLab repository and clone the required specs from there. In the project’s README, you will also find some information on how to get started on this.
