It's one of Linux software distribution systems. Actually, you can install snap packages on Mint.
Snap applications run in sandbox instead of having direct access to the system. So, you might experience low performance and other possible issues.
Snap packages contain all their dependencies. Therefore, you will download and store a lot of copies of the same dependencies.
I don't recommend using snap, unless you really need it's features.
Thank you for the recommendation. I won't be using snapstore features until I learn enough.
I was reading that it's also 'dangerous' for the system to use PPA libraries, is that true?
The danger here would be equivalent to installing 'windows .exe's' from untruthful sources?
As you're probably aware in Linux you install software through packages, which are normally hosted on servers. I wanted a distro to be able to access those packages at will even without an internet connection. With Debian you can download those packages in separate ISO's and build up an offline repository.
I don't know which distros offer this besides Debian, but for my use case it's been helpful. The only downside is that it takes some storage space (100+ GB).
Package maintenance is a blessing in Linux compared to Windows, thus I see your point. Really nice. This is good for backups it seems, the price is storage size though.
So you can build custom distros, based in 'official distros' with pre installed apps just like Android with root?
• What are the advantages and disadvantages of using two OSs in the same PC?
Honestly, no advantages. Disadvantages of wasting hard drive space, intricacies of sharing files between two OS's, more complicated bootloader setup, and the wasted time of switching from one to the other.
• What are the advantages and disadvantages of using ONLY Linux (any distro / comparison of distros, if you want to explain)?
Advantages of no wasted space, simpler setup, no problems trying to share files. I never truly learned how to use Linux until I ditched Windows. So, if you want to learn Linux, throw away the safety blanket, and dive in.
• Does WINE really works well with Windows exclusive games?
Yes. In the past it was frustratingly unstable in terms of regressions. It always felt as if every game that they made work, broke two other games that used to work. This is largely behind us now, and the recent releases have generally just worked.
Thank you for your answer too.
I kinda agree with you and with everyone else that said Dual Boot is kinda annoying.
As I said earlier, Im doing Dual Boot right now, almost ditching Windows completely.
File management with two systems feels weird.
Talking about WINE, I tested it with two windows games (GOG versions: Cyber Hook and Dragon's Dogma Dark Arisen).
Cyber Hook played well, with some arctifacts in ground textures, and some fps loss.
DDDA played really well, no graphical issues, but with constant stutters and fps loss in effect-heavy situations.
Thanks everyone for the answers. They're really helpful.
