Agreed. You need to be willing to migrate to FOSS software or else “switching to Linux” will be a total failure.

I think the key is you need to find FOSS software that works for you before migrating your OS. Most FOSS software will run on windows and sometimes MAC.

1-2 and 3 will be hard. You can find many tools that do something similar but it won’t be perfect. There are a few different music managers, and for office libreoffice is the go to.

4. try digikam, it supports all OSes

5. googling “Fujitsu snap scanner Linux” yielded a few blog articles on the matter. Seems it should be supported.

What’s your goal? Is it safe to match is a very open ended question.

Take RHEL, it’s meant to be a paid distro for enterprise, something Debian isn’t. But you could draw similarities too.

What’s are you trying to learn?

AMD

There are tools like rss bridge that can be a big help: https://github.com/RSS-Bridge/rss-bridge

YouTube wise I use invidious rewrite rules

I’m kind of addicted to miniflux.

I use it to aggregate my RSS l, GitHub release notes, & YouTube feeds so I can stay up to date

From what I understand nexcloud isn’t a mail server, only a client. I’d need something that can act as an SMTP bridge to actually send emails.

Proxmox is meant to be an appliance. Meaning, you shouldn’t mess with the base OS .

If you want a desktop it might be better to make a dedicated VM in proxmox for it.

Don’t you need the JRE to run Java code?

Nope, it seems to just work!

I’ve found it best to avoid the pacman repo. It can leave my system in such a weird inbetween state. Seeing as you mostly want codecs I tend to prefer flatpaks for VLC, Firefox, etc.

If you insist on pacman, just wait. If you try to dup and have a conflict it means that either pacman or suse repos aren’t all updated so hold on a few days and you should be able to dup with no issues.
