Use either BTRFS (no idea if Mint supports that) or LVM with EXT4 or F2FS. F2FS is used in Android, stable, fast, simple, flash optimized. Ext4 is also based.
Dont separate / from /home if you dont use the above setup. If you do, partitions can resize dynamically so no problems here.
Installing multiple OSses is messy, avoid it.
Windows Updates may remove GRUB and eat the partition. If the partition is still there, you could reflash GRUB with dd.
Disk encryption is a single checkbox in every installer I tried. It doesnt use the TPM so it works everywhere, while not as fancy as Android on a Google Pixel.
Absolutely do it.
Most often you only encrypt the / partition and not the boot. And no you dont touch Windows so no issues.
Tons of people use GDrive and Dropbox. It supposedly works.
On a traditional Distro I would leave the system as it is and install everything from Flathub. It is preinstalled and configured on Linux.
Traditional Distros are extremely messy and build up Entropy, i.e. randomness. You just do random shit everywhere and after a few months or years you have issues that nobody can reproduce and you need to reinstall.
That is why I am happily on Fedora Atomic Desktops (Kinoite, KDE). OSTree is heaven.
If you stick to Flatpaks you will not change the system at all, the apps are separated. So it will likely not break at all.
Ironically, while the “immutable” (managed) systems are used with Flatpak a lot, it is the traditional ones that should use it, as they dont have mechanisms like rpm-ostree reset.
Yeah for sure, thats the pdf.js also available in Firefox.
Why do you specifically want this in TB?
Firefox Flatpak worked normally via the portal for opening the PDF. I think Thunderbird defaults to sending a file as an attachment to a new empty mail.
they should have included the security patches from the get-go
I dont know how Ubuntu does that stuff, but universe is community supported only. It is required for many normal packages, so yes you could say their service is not good enough but hey, its free Software.
If you dont pay a cent you have like nothing to complain
I think they are just referring to the Ubuntu pro ads.
This is not spam. If you have random outdated packages from the universe repo on your system it will tell you that they would ALSO offer support for those if you get Ubuntu pro.
Maybe too often, idk. But Linux Mint will “fix” this by also running these old maybe insecure packages but not even offering security fixes.
People need to step down their weird Linux-entitlement horses, and get that Free Software is not free as in free beer.
There is literally not a single useful comment here.
You have packages from outside the official main repo, in the universe repo.
You are using a stable Distribution so packages are frozen and need backported security updates.
You dont get them for the optional universe repos, but if you give them a bit of money (or afaik Ubuntu pro is even free for a few devices) then they will also support these 3rd party packages.
It is an optional service, they warn you that you use outdated packages, and offer a solution.
I dont use Ubuntu and Snaps are crap, but this is totally fine.
