I’m sick of the terrible latest version 6.x libreoffice.
I don’t know why they ruined Libreoffice like that.
Anyway I found out how to downgrade for Fedora and Archlinux respectively.
Fedora
$ sudo dnf remove libreoffice*;
$ sudo dnf clean all;
https://downloadarchive.documentfoundation.org/libreoffice/old/5.4.7.2/rpm/x86_64/
download: <<libreoffice_5.4.7.2_linux_x86-64_rpm.tar.gz>>
$ tar xvzf LibreOffice_5.4.7.2_Linux_x86-64_rpm.tar.gz;
$ cd LibreOffice_5.4.7.2_Linux_x86-64_rpm/RPM;
$ sudo rpm -i *.rpm;
Archlinux
$ sudo pacman -R libreoffice-still;
$ sudo pacman -c;
http://archive.virtapi.org/packages/l/libreoffice-still/libreoffice-still-5.4.7-3-x86_64.pkg.tar.xz
$ sudo pacman -U libreoffice-still-5.4.7-3-x86_64.pkg.tar.xz;
