Libreoffice fonts missing

Version: 6.4.4.2 in PClinux KDE x64

I have an old document with Tahoma and Ariel font text. I’ve opened it and I can edit text but the selected text font can’t be changed. None of the fonts are listed in the font drop down menu.

If I start a new document, all the fonts are listed.

How do I make all the fonts available in the old document?

Fonts are managed by the operating system and not by any application. LibreOffice comes with a few fonts, but “Tahoma” and “Arial” (typical MS fonts found on Windows systems) are not among the provided fonts. You should check you distribution repositories, if it provides something like “Microsoft Core Fonts”, which could be installed.

I found a work around. I can highlight the text then copy the name of the font into the menu, press enter and the text updates. It seems a LO matter since the all fonts are available in a new document. Why would LO not make all fonts available to a old document?

But above you wrote : “None of the fonts are listed in the font drop down menu.” and now you tell "it seems a LO matter since the all fonts are available in a new document* - don’t need to understand this.

If I open the old document and the only font listed in the menu is the name of the text selected, yet when I open a new Writer document, type in some text, then select the text and all the fonts are listed, then that would seem to be an LO matter rather the OS?

Maybe its an ancient format. If you Save As [another name] in a current format does it come right?

Updating to LO 7.0 has solved the problem. All fonts are now present.
