Why does installing wine (for example) require removing 2GB of good packages?

I have a situation where:

sudo apt-get install winetricks 

Results in:

 The following packages were automatically installed and are no longer required:      aglfn apturl apturl-common asymptote-doc biber ca-certificates-java catdoc cdparanoia cdrskin cmake-data context      ...  Use 'sudo apt autoremove' to remove them.  The following additional packages will be installed:      fonts-wine libwine-development wine-development wine64-development  Suggested packages:      ttf-mscorefonts-installer winbind playonlinux wine-binfmt dosbox libwine-gecko-2.47 wine64-development-preloader aria2 tor  Recommended packages:      libcapi20-3 libodbc1 libosmesa6 wine32-development  The following packages will be REMOVED      appmenu-qt asymptote cdrdao chromium-codecs-ffmpeg-extra clang clang-6.0 cmake cmake-qt-gui compiz compiz-gnome dvd+rw-tools      eog evince firefox g++-5 g++-5-multilib g++-9 gcc-5 gcc-5-multilib gcc-9 gcj-5-jre-lib gfortran-5 gnome-sudoku      ...  After this operation, 2,032 MB disk space will be freed.  Do you want to continue? [Y/n] 

Why? I don’t understand why installing winetricks would possibly cause g++-9 and spotify-client (and 2GB of utterly essential applications) to be deleted. Can I not use these packages simultaneously?

EDIT: It has even deleted my ubuntu-desktop and nautilus

I gained access to wine via

sudo add-apt-repository ppa:ubuntu-wine/pp 

I am on 18.04

Can a polymorphed creature use class features that don’t require speech or hand gestures?

The Polymorph spell states (in part):

The target’s game statistics, including mental ability scores, are replaced by the statistics of the chosen beast. It retains its alignment and personality.

The creature is limited in actions it can perform by the nature of its new form, and it can’t speak, cast spells, or take any other action that requires hands, or speech.

So, can a polymorphed Paladin use their Divine Smite class feature? It expends a spell slot, but it is not a spell, and as far as we can tell does not require hands or speech.

We know (based on the 10th level Transmutation Wizard feature) that a wizard is supposed to be able to polymorph herself, and we can assume that she is also supposed to be able to maintain concentration needed to stay in the new form (otherwise it would be a pretty useless ability). This is (as far as I can tell) not something any of the beasts eligible as polymorph targets can normally do. So it is clear that the polymorphed creature maintains some abilities from her old form. The question is which ones.

The Druid’s Wild Shape ability explicitly says you can use class features, while Polymorph does not, suggesting that you can’t use class features while polymorphed. However, Wild Shape also explicitly says that you can continue to concentrate on a spell (see below, emphasis mine), and Polymorph does not, yet we believe that a polymorphed creature can continue to concentrate on the polymorph spell. So the fact that Wild Shape explicitly allows something and Polymorph is not explicit about it does not necessarily mean that the polymorphed creature cannot do those things.

From Wild Shape rules:

You can’t cast spells, and your ability to speak or take any action that requires hands is limited to the capabilities of your beast form. Transforming doesn’t break your concentration on a spell you’ve already cast, however, or prevent you from taking actions that are part of a spell, such as call lightning, that you’ve already cast.

So, since Polymorph is silent on the question of whether or not class abilities can be used, and states only that the polymorphed creature cannot perform actions that require hands or speech, how can we best determine whether (RAI) polymorphed creatures maintain any of their old abilities beyond spell concentration?

Does Shadow Lore require the Bard to physically whisper, and could the target or a nearby creature detect this?

A 14th level College of Whispers Bard gains the following class feature:

Shadow Lore: As an action, you magically whisper a phrase that only one creature of your choice within 30 feet of you can hear. The target must make a Wisdom saving throw against your spell save DC. It automatically succeeds if it doesn’t share a language with you or if it can’t hear you. On a successful saving throw, your whisper sounds like unintelligible mumbling and has no effect.

If the target fails its saving throw, it is charmed by you for the next 8 hours or until you or your allies attack or damage it. It interprets the whispers as a description of its most mortifying secret.

While you gain no knowledge of this secret, the target is convinced you know it. While charmed in this way, the creature obeys your commands for fear that you will reveal its secret. It won’t risk its life for you or fight for you, unless it was already inclined to do so. It grants you favors and gifts it would offer to a close friend.

When the effect ends, the creature has no understanding of why it held you in such fear.

(pg 16, Xanathar’s Guide to Everything)

When using Shadow Lore, would the Bard physically whisper something that only the Target can hear, or is it more like a telepathic whisper that the target hears?

Would the target, or a nearby creature, be able to tell that Shadow Lore was used and potentially who used it?

How can I configure Ubuntu to require answers to random math problems in place of a password?

For the home Linux laptop (running Ubuntu 18.04), for the kids, I would like to be able to configure the computer to require answer(s) to randomly selected math problems to log in, rather than requiring a password. (For a specific user account only, for graphical login only.)

I’ve searched the internet but haven’t found anything about this. It doesn’t seem likely that I’m the first one to think of this idea, but internet searches do suggest that. 🙂

Security isn’t an issue since the only people with physical access to the computer are all trusted. (If there is anything I should configure to disallow SSH access or for other security concerns, you could mention it, but I doubt my ISP would let port 22 traffic through from the internet anyway.)

The benefits should be obvious, but to be explicit about them – the point is that there could be a mild barrier to “getting screen time” that would involve something a little bit educational.

I am currently using Gnome with sddm as the display manager, but I don’t know if that really matters.

Why doesn’t the sentinel feat require a saving throw? [on hold]

Sentinel feat is overpowered and can be fixed with a saving throw. (No other ability or spell in the game allows you to affect another creature’s movement without some sort of save)

Sentinel – Whenever you hit a creature with an opportunity attack, its speed drops to 0 for the rest of the turn. This stops any movement they may have been taking. (Unlimited uses)

Compare this to similar attack abilities that have added effects.

Trip Attack:

if the target is Large or smaller, it must make a Strength saving throw. On a failed save, you knock the target prone. (limited uses – superiority dice)

Pushing Attack:

if the target is Large or smaller, it must make a Strength saving throw. On a failed save, you push the target up to 15 feet away from you. (limited uses – superiority dice)

Disarming Attack:

target must make a Strength saving throw. On a failed save, it drops the object you choose. The object lands at its feet. (limited uses – superiority dice)

Goading Attack:

target must make a Wisdom saving throw. On a failed save, the target has disadvantage on all attack rolls against targets other than you until the end of your next turn. (limited uses – superiority dice)

Menacing Attack:

target must make a Wisdom saving throw. On a failed save, it is frightened of you until the end of your next turn. (limited uses – superiority dice)

How can I decide if my homebrew item should require attunement?

Attunement slots are an important tool for maintaining game balance – especially in high magic settings where magic items are common.

If I’ve homebrewed a new magic item for my players, how can I decide if balance-wise this item should require attunement or not?

It’s fairly trivial to say that the most powerful items should probably require attunement, whereas the least powerful probably shouldn’t. But, in between these two extremes, where should the line be drawn?

  • Are there any guidelines in offical materials for when homebrewed items should require attunement?
  • Or, can any guidelines be sensibly inferred through careful analysis of existing official magic items (contrasting those that do require attunement with those that do not)?

Does Air Walk Require a Fly Action?

The end of the Fly action states:

If you’re airborne at the end of your turn and didn’t use a Fly action this round, you fall.

However, it also requires you to have a fly speed. While this makes perfect sense for the Fly spell, the Air Walk spell says:

The target can walk on air as if it were solid ground.

This gives the target the ability to move through the air, but it doesn’t specifically say it’s a move speed. Additionally, if the target treats the air as solid ground, they wouldn’t normally need to spend an action to not fall through the “floor.”

My concern is that these two spells are the same level, but seem to function very differently. Does the Air Walk spell necessitate the usage of the Fly action, or does it literally allow you to stand on air?
