I'm trying to left behind the Apple company so just started using Ubuntu.
- What software do you recommend for editing PDFs? Or to fill out and SIGN templates? With the Mac I use Preview, is there something similar to this?
- How can I record a video of the screen with sound coming from a mic?
- I'm having some trouble installing software, some of the instructions mention to install "AppImageLauncher" but I got an error when trying to do it...
| 1. What software do you recommend for editing PDFs? Or to fill out and SIGN templates? With the Mac I use Preview, is there something similar to this?
If by sign you mean "insert an image a scanned signature" (and not a cryptographic signature), LibreOffice can edit PDF natively, see How to Fill and Sign PDFs in Linux.

SimpleScreenRecorder works fine for that.
For 1. I like PDFArranger to add/remove/reorganize PDF pages and Xournal++ to edit PDFs.
