I couldn't agree more with BrotherBob and his suggestions/links!
Also, a third good option I would add is Puffaway's v14 of the xls calc by Scubabatdan stickied on this subforum(one of the last posts is Puffaway's link). It's fixed to work better with libreoffice and also works nice with google drive/docs and zoho sheets as renderer. I use this now instead of e-liquid-recipes, since it has gram meassures with adjustable densities, whereas the e-liquid-recipes is alittle off and hardcoded.
On linux there's almost always an alternative, or several ones to match up
Btw, I'm an arch linux guy myself
