Two Libras share every instinct, including the blind spot. Here is what that makes easy, what it makes invisible, and what actually decides whether it works.

Libra and Libra are 0 degrees apart on the wheel, which makes them a conjunction. The angle is the relationship.
The short answerTwo Libras are a conjunction: the same element, the same mode, the same instincts. That makes the relationship unusually easy to be inside and unusually blind, because Libra's weak spot is present twice with nobody to balance it. The pairing works when both people have other things in their charts pulling in different directions.
Before any of that is useful, the caveat that most compatibility pages leave off: comparing two Sun signs is the weakest form of this technique. It uses one placement out of roughly forty, and it ignores the Moon, Venus, Mars and the rising sign, which between them do most of the actual work in a relationship. What follows is genuinely true about the structure between these two signs. It is not a verdict on two people.
The structure: a conjunction
Libra sits at position 7 in the zodiac and Libra at position 7. In astrology that distance is itself the relationship. It is not a metaphor: the same angle between two planets in one chart means the same thing, and it is read the same way.

What works
You do not have to explain yourself. The pace, the priorities and the way you handle a bad week are already shared, and that removes an entire category of argument.
Both of you start things. Two cardinal signs produce a great deal of initiative and a quiet competition over who is leading.
What strains
Nobody in the room compensates. Whatever the sign is weak at, this pairing is weak at twice, and there is no second perspective to catch it.
The specific version here: Libra keeps the peace at its own expense. In a pairing of two, that habit meets itself, and neither of you is in a position to call it. It is the single most common way this match goes wrong, and it is entirely manageable once it has been said out loud.
How it tends to go, day to day
Three places the structure above actually shows up, rather than in the abstract.
At the start
Fast, and unusually comfortable. Two Libras recognise each other early and tend to skip the stage where people work out how the other one operates, because they already know. The thing to watch is that recognition is not the same as compatibility, and this pairing confuses the two more than most.
In an argument
Both cardinal, which means you escalate at the same speed and in the same way. Two cardinal signs both move first, so a disagreement becomes a race rather than a conversation.
Over years
These pairings are decided by whether the effort stays interesting. There is no structural glue here, so what holds it together is chosen rather than given, which is either the weakness or the whole point depending on who you ask.
What actually decides it
Four placements do more work in a relationship than the Sun does. The first three only need a birth date; the fourth needs a birth time, and so does knowing which part of each person's life the other one lands in.
Moon. What each of you needs in order to settle. Two people whose Moons get on can survive a great deal that looks unworkable on paper.
Venus. What you each find attractive and how you show affection. Mismatched Venus signs are the most common source of "they love me, but not in a way I can feel."
Mars. How each of you fights, and how fast. This is the one that decides whether an argument clears the air or lasts three days.
Rising sign. How you meet each other, and which houses each person's planets fall into in the other's chart. This needs an accurate birth time for both of you.
There is no incompatible pairEvery combination of two signs exists in long, happy relationships and in short, miserable ones. What the structure above describes is where the effort is likely to go, not whether the relationship can work. A pairing that has to work at it is often more durable than one that never needed to, because the skill got built.
If you are reading this about someone specific
Take the structural part seriously: a shared blind spot is real and it will show up.
Take the character descriptions lightly. They describe one placement each.
Find both Moon signs before you conclude anything. It is the single most informative addition to a Sun sign comparison.
Two Libras understand each other immediately, which removes a great deal of friction. The difficulty is that Libra's blind spot is present twice with nobody to catch it. It works, and it works best when the rest of both charts differs.
How many signs apart are Libra and Libra?
They are the same sign, which is a conjunction.
What do Libra and Libra argue about?
The shared habit. Libra keeps the peace at its own expense, and in this pairing there is nobody doing the opposite to balance it.
Is Sun sign compatibility reliable?
It is the weakest form of the technique. It uses one placement out of about forty and leaves out the Moon, Venus, Mars and the rising sign, which do most of the work. It is a real structure, but it is a small part of the picture.
